I have a same dilema, to be hones, I plan on only playing (caring for) new Age of Conan. On my 20" Samsung LCD I play 1600 x 1200.
I assempled the rig a year ago (E4300 @2.7 Ghz, 4 Gb RAM, Vista 32) and I just upgraded my year old 7900 GS 256 with a new EVGA 8800 GTS 320 Mb.
Than a friend who upgraded his EVGA 8800 GTS 320 with new 8800 512 GT, gives me his old one (exact same as mine), for my second PC - but it can't fit (I have PCI Express but damn card can not fit!)
So do I SLI?!
But my GIGABYTE GA-965P-S3 Mobo does not do SLI...
So where is the bang for the buck (I have $$$ but don't want to spend too much on PC that is a year old):
1. RMA to newegg 8800 GTS (tho I cut the box and mailed in rebate, can I?) buy 9600 GT or 8800 GT 512?
2. Buy for $100 Asus P5N-E SLI mobo and SLI these two?
With 7900 GS I was getting 4,400 on 3DMark2006, oc-ed 4,700, with 8800 GTS 320 I get 7,900 OCed to 600/500 and 900/780 I get 8,900. If I SLI two of them can I OC???
My PSU is ENERMAX EG495AX-VE FMA 485W, is that enough?
Thanks for your help!
