Thanks for the advice. I stuck with the 5770. I did a ton of reading on the 5770 and 4890 debates and went back and forth a thousand times but not being a huge gamer and also not using huge resolutions when I do help me make the decision.
I do have one off topic question about the build - I took my hard drive out of my current pc - what will happen if I connect it to the new pc and boot up? (I have Windows 7 loaded)
