Hi, I have an AMD 64 X2 5600+, 3 GB RAM, and a BFG 8800GT 512MB OC. I have searched around the forums, but I could not find any direct results, so I apologize if this has already been addressed. Now, I am not very knowledgeable when it comes to computer, but I do know enough to get me around. I bought my HP Media Center PC around November of last year. My 8800GT is wonderful, but I have a feeling it might be bottlenecked my CPU.

What is the Intel equivalent to the 5600+ and how does the 5600+ hold to current processors?

What are generally the CPUs (Intel and AMD) people are looking at now? I have a feeling that my CPU is pretty old, for I can't seem to find it on any retailer sites.

I have pretty good performance in the UT3 demo. I'm interested in Gears of War for the PC. Since Gears of War uses the same engine, does that mean I should get around the same performance (I know that this should be in another forum, but I'll leave it here for now)?

Thank you in advance. :)
