Hello! Well I've found that my CPU is bottlenecking my GPU, because when I run benchmarks, and oc my video card's core even 75 mhz I see nearly no difference over many games incl. Crysis. So to me, its time to overclock! I would like to discuss some of my options here. To start my system specs: Rosewill 530W PSU (41A 12V-rail, 80PLUS Bronze certified) ASUS EAH4870 DK 1GB Gigabyte GA-EP45-UD3L Motherboard (P45 Chipset!) G.Skill DDR1066 Ram 2x1GB Intel Core 2 Quad 8200 The cooler I expect to purchase is the XIGMATEK HDT-SD964 Here I have read that a few people managed to get up to a 3.3GHz clock on this CPU, and I would be extremely satisfied if I got a 2.8 to 2.9 GHz clock. (22-26% OC) Just so you know: 7x multiplier stock 333mhz FSB. Are my system components good enough for this venture? Will I have to raise my CPU voltage significantly?
