I kind of wanted to get best i can get for my mobo 750i ftw .
Its got qx 6700 no oc I was thinking of getting 690 gtx during black friday but have no idea if it would work in my set up anyone know this answer. Greatly appreciate it 

There are different types of games, but two main groups: CPU-intensive and GPU-intensive.  All games are still run by the CPU and only the CPU tells the graphics what to draw.  What ki11joy92 is alluding to is that the QX6700 is dated in the sense that there are faster processors available even at the same frequency since Intel has been changing the design of the processor over the years.  But keep in mind, many active members of these forums do choose to keep up with technology so much that it blinds them with how to deal with older hardware other than suggesting you keep up.

Fact is you have some leway in upgrading, you can only upgrade the fastest equivalent graphics card to what was possible back when Core 2 Quads were the big deal.  Back then in fall 2006 through 2007, 8800GTX was king and only up to 3-way SLI was possible towards the end of 2007.  Since not everyone overclocks their CPU, a modern equivalent to a triple of 8800GTX's is the fastest you could get before better fails to scale.  

Equivalents to a triple of 8800GTX include GTX465, GTX560 and GTX660-- If you don't want to overclock the CPU or change your setup, these are the fastest cards you could get without worrying about scaling issues.

The idea is that if a graphics card upgrade doesn't scale as expected, it is usually held back by another component, and it is usually a slower CPU; thus why we overclock.  But it isn't just about frequency since Intel changes the design architecture every few years.  For your case, an overclock could allow for a faster graphics card than what you have, in the sense that the CPU tells the graphics card what to draw. 

By the time 3.2GHz QX9770 appeared in 2008 before the new generation Core i parts, people would use multiple GTX200 series cards, but back then the maximum was 3-way SLI whether you had CPU overclock or not.  Therefore, if you overclocked your QX6700 to the speeds of QX9770, then the maximum you could support would be the modern equivalent to 3-way SLI GTX280.  According to Anandtech reviews linked below, if we compare with the game Crysis Warhead at 1920x1200, 3-way SLI GTX280's comes close to a single GTX680, but not GTX690 which has the power of two GTX670's actually.

In other words, a GTX690 may require a CPU overclock that your QX6700 cannot sustain, i.e. well over 4GHz because it is the equivalent power of six GTX200 series cards from the time of Core 2 Quad.  

But if you have $1000 to spend of a GTX690, I rather suggest you get a new Core i5-3000 series processor in a Z77 chipset and a single GTX680 with new 1080p display if you don't have one.  Ironically, because you've waited so long, while you'd have to do this daisy-chain research to find a some context, a full on upgrade would be easier than not changing everything.

Also, even if you had the best CPU and GPU combination, a low resolution will bottleneck which forces CPU-intensive, and with a QX6700, it would defeat the purpose of any graphics card you upgrade to if you had a lower resolution.

Lol i waited cause my laptop is i7 with 650 gtx 16 gig of ram but since i wanted uae desktop for my 50 inch tv again . Well lol i wanted upgrade a little but replacing everything is a slight pain.

umm just to correct you here, the Core2 showed that it bottlenecked sli 8800GTX's to an extent and people saw gains with the i5 and i7 cpu's and with triple even greater gains.
