it's an old hobby of mine which kinda escalated after my 34 year old computerclub died. I'm like I could sell them but since I am a retro gamer the only serious game I play online competitively wise is Descent 1 & 2.
Games for fun are CoD MW2, JC2 and some games that are upcoming.
The Dual Opty 285 E6 with with GTX 480 uses the Samsun SyncMaster B93 if I would be attending to a LAN, but due to my illness that isn't possible anymore, even though it's my good old LAN box and it never let me down.
the others are just there for use, old programs to new ones, I envy building 2CPU based system as I have been doing since January 28, 2000 and it's just something else that them everyday Core i7, I55 of Phenom II or FX based 1CPU builds, I interest server hardware a lot and as I build along I also make a neat collection on the way
As Overclockings goes or 3D mark that has never gotten my attention or interest, 2CPU Server hardware has always gotten my main attention also due to the higher quality hard components used that are made to last longer than normal conventional hardware under any type of workloads for at least 5 years or more. And that has clearly proven to me as the following systems go:
283.) Gold Leader - Gradinko 253.) Gold Leader - Sveta 252.) Gold Leader - Firefox Gradinko was built on January 28, year 2000, was used to March 20 2003 I sold it's motherboard CPU's and Ram to a good friend for 550 EURO, on March 28 of 2008 I rebought it with the same CPU's and Motherboard, same ram, but with a Club3D 9700 Pro, SB Live 5.1, Addtronics 7896 A Server Tower, 80 + 160GB 7200 ATA 1000 Matrox HDD's, Nec 1300A DVD Rewriter , 325 Watt Enermax PSU all for 100 euro, it was a file/game server at his work for 5 years it ran 24/7 without crashing or the need to be rebooted, it also survived a 52 hour blackout, thanks to it's 72 hour UPS power backup system it was attached to, and it was cleaned every month, so I guess all the good care it was given that this made it live it's life which it is doing now :)
It's 12 years and 9 months old as Mobo CPU's and ram goes and t has never failed me since Jan 28, year 2000.
As for Sveta, she was built in 2004, with OpteronDP 244 CG CPU's, I upgraded her once with OpteronDP 248 CG's and now she has OpteronMP 850 CG's the max CPU's supported by the MS-9130 K8T MAster-2 FAR, i don't use this system much but as usual it still functions dead stable, it's fans are a bit noisy but I don't mind I like how they roar as if it's still willing to come alive rofl! the VGA card the HIS HD 3850 ICEQ3 Turbo AGP 512MB 256Bit GDDR3 aka HIS HD 3870 AGP 512MB GDDR3 was purchased in 2008, still it does it's job fine for them older mid aged games of 2002 to 2006. This system is 8 years and 4 months old and it still functions fine even all the DX9 games out there run fine on it @ 1440 x 900 x32, so yeah, even being over 8 years old you cans till game with it without issues.
As for Firefox SMP 2006, this was a rebuild but the tech of the hardware dates back to Q4 2005 Q1 2006 :) Don't remember the precise date, but it's about 6 years and 5 months old, as it's tech goes :) the only advanced thing in it is the EVGA GTX 480 from 2010, the Auzentech X-Fi Prelude 7.1 is from 2007
This system runs all the games I play in DX9, 10 and 11 @ 1920 x 1200 just fine on it's HP ZR24w 24" S-IPS Panel, it's GTX480 and it's PCI-E 1.1 x16 slot is a major saviour to this system :) For lans I use the Samsung SyncMaster B943 which has a reso of 1440 x 900 x32 also a piece of cake for it to handle with
But even my main is from 2009, it has two EVGA GTX 680 SC SE's now and really Dual Opterons last long as they have proved me, you'll never see me go 1CPU again, they just gave me a bad experience the X58 setup like the X79 setup gave me living nightmares, they cost me too much and I didn't get out of them what I was expecting.
So in the end I only buy high quality server hardware as it proved me the best reliable experience ever as life span goes, mainly lifespan of the hardware it's self.
Selling them old PC's is possible but what I'd get from them isn't worth it to me, so keeping them and making them useful seemed more logical to me
Sorry for making this a long read, my Autism makes me go on and on about somethings :X
