I don't really care, as long as it looks good and plays well. I just want something high-end, something I can use to play high resolution (1280x1024) games.
Anyway, g2g, ill come back to this site in a little bit.
You can get an E6600 and a P5B-E or DS3 for around 470 or so and that would be your budget but see...you would NOT see much improvment in games as you do understand that in no way are X2's much slower than Core 2's right?
Your CPU is a very good one for gaming and you really shouldn't worry about upgrading it until the new Agena comes out in a few months.
For now if you want to see really high FPS then get an 8800GTS 640mb for around 350 bucks. Your CPU is a good one and not slow at all.
