For just about your budget, Sager has this notebook: http://sagernotebook...del_name=NP6658
Take the offer for the $35 CPU upgrade, and you have a damn nice machine for just about on your budget.
If you were willing to spend $80 more, you'd could get this machine though: http://sagernotebook...del_name=NP7358
I think you'd be a fair bit happier with it for that minimal increase, but if it's not realistic then it's not realistic. I understand.
They're both substantially better, especially for what you're looking for, than the machines I'm seeing on Newegg in that price range, but that's to be expected. Sager laptops are always kickass on both price and performance.
Edit: MAKE SURE if you order from Sager you select the 8GB Dual Channel option.
