i whent form 775 to 1155 and i dont even want to go back to 775,, u can use 1156 aftermarket coolers for 1155, just not the cpus

So you can or can't? Be more clear

direraptor22
He meant that you can use the CPU coolers with 1156 compatibility on a 1155 mounting platform, but socket 1156 CPUs (i5 760, i7 860, 875K etc) will NOT be able to run on socket 1155 mobos.

Short Version:
I think if you ever intend on multiples of any $250 video card or greater, then you shouldn't touch the mainstream socket LGA1155, don't let the appeal of high overclocks fool you unless you never intend on more than one graphics card.  Most folks upgrade graphics more often, so you have to consider future upgrades if you intend to keep the mainboard.  It really doesn't matter of the highest-end now doesn't need more than 16 lanes unless you never upgrade until you change the board.

Long Version:
By market, the LGA1155 socket succeeded the same market that used the LGA775 socket for all except the extreme chipsets, X48 and 790i -- latter went to LGA1366 with X58.  Since there was no AMD competition nor and nVidia licence for LGA1366, Intel will continue to milk that market untl the successor using a single LGA2011 socket comes this fall.

There is no rule you should stick to a market, you can get whatever you want, just know that Intel does their homework: Their products are catered to a general audience. What primarily separates LGA1155 and LGA1366 (and the LGA2011 successor) is the number of PCIe lanes they support as the mainstream market isn't high-end multi-GPU.

There is no rule on how often you got to upgrade, but I advise considering the one after from a future-proof sense because most here seem to only upgrade for present uses.  For instance, say you got for dual 570's, they together don't need more than 16 lanes of PCIe and LGA1155 would seem like a great choice -- but as soon as you get the next set, it will be physically bottlenecked by 16 lanes and you can't get more without changing the board.  IMO, it would suck to upgrade often and advise again such a gamble, but then you're reading a post from someone that prefers years apart each system upgrade.

                 My 775 still owns. If it's not broken........      ;)

nivektThank you for the input everyone. I have decided to hold off. The only factor in my equation that I failed to mention is that my current GPU is a GTX 480, instead of a GTX 295.0

I upgraded from the same CPU to the exact one you mention, and I have noticed a massive performance differance. But now I do a lot of movie editing/processing.
But I have noticed my games do run smoother, and that I can use higher graphics settings....(using a GTX 280).

FYI, this forum is mainly an enthusiast forum:  They spread confusion by simplification as if enthusiasts are independant of anything else Intel makes.

Short version:
The issue of which socket is simply a matter of which graphics cards used.  If you intend on a second 480 someday, LGA1155 is still a good fit; but not if you get a third 480 or some future high-end pair.  Higher CPU overclock will not compensate for not enough PCIe lanes.  LGA2011 has more lanes by default. 
 
Long Version:
There will be other Ivy Bridge processors in other sockets on other debut schedules.  For example, a CPU fitting into LGA2011 will have more features than one fitting into an LGA1155 socket, for a premium.  They won't physically fit in each other and Intel will separate the brandnames so you can tell which goes where.  For example, Core i7 900's only worked with X58, in single-LGA1366 boards.    
 
Intel segmented high-end desktop away from mainstream as mentioned, into the server socket LGA1366 because the fact is we have more in common with them for our need for more memory bandwidth and PCIe land bandwidth.  So begining with Nehalem (and the Westmere shrink), their first generation "Core i" series used two sockets for the desktop CPU market.  This is being repeated with the second generation of "Core i" CPUs using the Sandy Bridge architecture, where LGA1155 holds mainstream variants limited to dual-channel DDR3 and 16 lanes of PCIe 2.0 while Intel will later debut a motherboard with a single LGA2011 socket for those that want quad-channel DDR3 and 40 lanes of PCIe 3.0 -- it is more future-proof, but not as affordable. 

Ivy Bridge is like Sandy Bridge -- and Westmere and Nehalem and Penryn before it -- they are all just codenames for the entire architecture or shrink that Intel designs years in advance.  This technology is applied to all of Intel's processors regardless of brandname or which sockets they go into -- but they have their own schedules and separated by features useful to a target customer type whether by number of DDR3 channels, PCIe lanes, whether their chipsets have how many USB 3.0 or SATA 6Gbps port, or whatever.   In otherwords, there isn't just one CPU type called "Sandy Bridge" or "Ivy Bridge"; there's plenty.

If you upgrade let me know what you want for that Q9650.

How in the Earth did you manage to stabilise your Q9650 at 4.05 on a 780i? That'd take 450 FSB and I doubt the board would be semi-stable at all considering that you got a quad and this was close to all I could get out of my old dualie.

http://valid.canardpc.com/show_oc.php?id=1271613

I made it half-stable with 1X4 GB DDR2-1200 at some time but it wasn't worth it for the crashes, and I could have lived with 2 GB of RAM hence my XP X64, heh. Though, I keep paging file off now that I've 4 GB, I had to use it with 2 GB but it was alright because I had over 1.5 GB free on XP. I'd have been trumped on W7.

Anyway, why do you want to change platforms if you have a Q9650 at 4.05 Ghz? That'd be enough for any new game. Just get this and SLi those babies. http://www.newegg.com/Pro...x?Item=N82E16814127502 You can't get any better than that for $300 to SLi, you'll get to use Afterburner and it sounds like MSI has added some extra High-C caps over the reference PCB!

I got two 480's right now and I've seen %200 scalability in FurMark, it went from 80 to 160 FPS when I added the second card using 16X AA with high quality nV CP settings at 1920X1200. The difference in F.E.A.R was monstrous, it went from 150 FPS to 250 FPS avg. at 1920X1440 using 8X TR SS AA and all in-game settings maxed out with soft-shadows + 4X MS AA.

F.E.A.R has always played well with multi-GPU's so you can see the massive difference in raw power as usual on that game, even with new cards.

I'm running them off a Crosshair 2 Formula 780a with an X4 975 at 4.3 and they own. I don't know how I left this to the end but, you have to change your PSU even if you don't upgrade. That OCZ is a FSP Epsilon unit that'll end up with a horror story. See the "upgraded" version of the OEM of your unit here and decide on it's quality.

nivektGetting my OC was really easy. I have the FTW version of the board and it has solid state capacitors. Ive never had the problems with it that those with the regular 780i board have. 

Wow, that pretty disheartening about the PSU. That review made me laugh at how ridiculously bad that PSU is. Are you sure mine is the same one? Its the OCZ EliteXstream 900w. I got a it about two years ago via RMA when my GameXstream 850w died on me. The 900w has never given me any problems. Obvisoulsy if I decided to go sli with another GTX 480 I would upgrade. Thanks for all the info and links. Much appreciated.
