Looked up my GPU usage in msi afterburner and behold, in Crysis 1 it can get as bad as 54%. Anyway, I have an option to sell my AMD rig and upgrade to a sandy bridge setup at the cost of $110 or upgrading to an BE Phenom ii X4 rig at no cost. Would upgrading to sandy bridge fix my bottlenecking issues or would I be better off with a Phenom ii X4 @ 4ghz?
Phenom II X4 @4GHz is still slower than stock Core i5 2500(K).
Deneb architecture is already old (2 and half years since released) and thus not comparable to fresh chip like Sandy Bridge.
Sandy Bridge architecture seems very good in many games algorithm. You should know that Core i5 2500 can outperform Core i7 990X in games (but not in multithreaded application).
Upgrading to Sandy Bridge not only boost your performance but also lower your power consumption quite noticeable compared to 4GHz Phenom II X4.
If you plan to stick with AMD. Wait 2 or 3 months for Bulldozer to come out.
1GHz Turbo Core will come in handy for gaming.
