I build that small system also that you and some others helped me with from here when I first joined, It runs great.
Building up a better system now.
Also, Regretting selling my XFX 6950 and 460's a bit back,
Yep, Sold the 6950 because it was just sitting, ( But like you said , To late now lol )
I had ( Have ) a DELL 530, Wanted more punch, E7300 to E8600, 220 to EVGA GTX 460, 300PSU to Corsair HX 650 and Went to Ballistic 6400 4 gigs by recommendation,
That DELL was playing everything after the upgrade, Black Ops, BF2BC etc... Only problem was I couldn't OC the CPU. ( Ring a Bell? ) You guys help allot of people on here, So you probably won't remember.
Have another member also helping, Guidance,
What I have now
Gskill 4 gig
And other things..
and looking to go SLI
I game allot. So FPS is a big factor for me,
I had no Idea the GTX 560 was equal. May search for one of those also ( Alternative?).
