Hello... they have a great WEBsite, but at times need a location, for exact product available in your location... do you want a single space card or can you fit a Double space card into your case/computer? What kind of Video connector do you need for your monitor? Would you like HDMI for Dual monitor connection to your TV? Your Budget is very flexible for advanced features, and performance, want a little extra Spice?
You need to get at least the GTX 650 Ti or the HD 7770 but you'll need a 450 watt psu to power it up. If you are in a tight budget and dosn't want to get a 450 watt PSU, go for GT 640 or HD 7750. That would give you acceptable performance at 1366 x 768 resolution. Just don't expect too much on low end cards
