I personally have an ASUS F3SV-X1 as seen here http://www.newegg.com/Product/Produc...asus%2bf3sv-x1
I got XP on it and I run Crysis with a mix of high, low and medium settings. Works fine for me and I added and extra 40 bucks so I could get another gig of ram. Altogether it costs a little over 1300 for me. Speakers are not good though, use headphones. I use photoshop on it mostly though and it works great. Pretty cheap for what it does too.
