I recently upgraded my whole entire system from an AMD Athlon X2 platform to an Intel Core 2 Duo series platform because my processor was bottlenecking a new video card I had bought (an XFX Radeon HD 4890)
However, I managed to obtain another Radeon HD 4890 for really, really cheap and now have them in Crossfire X mode in my system.
The performance is fine, it's near what I expected but I'm just wondering if I would gain any performance improvements from upgrading processors, especially from a dual core to a quad core?
Intel Core 2 Duo E8400 (E0 stepping) clocked @ 3.83GHz (1.25v)
Artic Freezer 7 Pro CPU Cooler
Asus P5Q Pro Turbo Motherboard
4GB G.Skill PC2-8500 DDR2-1066 RAM (5-5-5-15)
2x Radeon HD 4890 1024MB GDDR5 in Crossfire Mode (one is an OC edition, the other is a normal edition, balanced both to reasonable clocks)
Basically what I was thinking of doing was upgrading from an E8400 to a Q6600? Upgrade or downgrade? Otherwise can anyone recommend me a better processor (without changing motherboards) that will give me marginal performance improvements?
The reason I'm asking is because in Grand Theft Auto IV, performance almost didn't change, and I heard that using a quad-core processor helps it a lot.
