PSU Thermaltake 500w topped out/ Motherboard ASUS M4A79XTD EVO 790X AM3 RT/ 6GB Triple Channel 1333Mhz DDR3/ AMD Athlon II X2 255 3.1GHz AM3 CPU Dual-Core Processor/ 2x 250 GB SATA HD's/ and possibly a 560ti or Radeon 6950/ none important stuff I thinking about buying a open PC case.
My question is how will I fare against todays big games.
your gonna struggle with games like bfbc2 and other games that like a quad core.
your gfx will overpower your cpu with a lot of older games...
as your system stands its top heavy with the gfx.
so swap out the dual core for a quad or lower the gfx...
my prefrence would be to change the cpu.
have you purchased this stuff already? I dont think your memory is compatible to your motherboard. as HEXiT said you will benefit from a better cpu, pairing a $50 cpu with a $250 gpu doesnt make sense. I would get a phenom ii x4 at the least.
Agreed with the others. Get a better CPU. Change it to a Phenom II X 4 945/955/965 BE, i.e if you have the budget for those. You'd also need a better PSU to power in either of those cards, you'll need some 700 W or 750 W PSU just to be safe.
560Ti will do well enough at lower resolutions - you should be able to get everything maxxed out and running fairly well. 6950 is around the same performance as a 560Ti (bit less in some benchmarks), though some 6950s can be flashed to become 6970s, so that's also something to consider.
