I just bought the Radeon HD 4870 1gb (hasnt come yet), and my friend told me something about how my cpu will bottleneck my gpu. I have a: amd athlon 4450e 64x 2.3ghz processor So i was wondering how much that would bottleneck my gpu and how i could overclock my cpu to run better (can't do it in bios) K thx btw im a noob to all this computer hardware stuff but im pretty decent with software.

You should google how far people have pushed that chip and under what voltages to begin with, and check who is using stock cooling etc. Now you said you couldn't change anything because of the bios. Is it a prebuilt pc?
Yeah, it's an hp compaq presario ----> here's the computer http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4555150&CatId=5140

Ok that would explain why the bios is locked. Honestly, don't worry about the bottleneck too much. If you want, pm me when you've got it set up, and we can compare benchmarks. I've got a better CPU, but worse GPU (4850) and if your average fps performance is better than mine you should be happy. Run "unigine" benchmark and pm me your results or something. I get 29.8fps. Specs in signature.
