I Had the radeon 7750 2gb in my system and it was good played all my games better then my previous Geforce GT520....expect GTA IV and Crysis 2 were very laggy and unplayable on max settings. I just purchased the GTX 550 Ti for 109.00 with 20.00 mail in rebate so for 89.00 not a bad price (radeon was 149.00 at best buy). I play every game out now at max settings with frame rates between 25-60 very playable imo. Some examples would be :
GTX 550Ti / Radeon 7750
Skyrim - min 27fps avg 44-60fps / Min 16-20 Fps Avg 27 Fps
Guild Wars 2 - min 20fps avg 33-60fps / Min 16-17 FPS Avg 24-27 Fps
Star Wars The Old Republic - min of 30 fps Avg 60 Fps / Min 20 fps Avg 30-40 Fps
Crysis 2 - Min 25 fps Avg 40Fps / Unplayable on Ultra Settings
Borderlands 2 - Min 24 Fps Avg 40-50fps / Min 16-20Fps Avg 30 Fps
GTA IV - min 16-17 fps Avg 30fps / Unplayable on Max Settings
System Specs
Processor Intel Core 2 Quad Q9950 2.83GHz
8 GB DDR2 PC6400 800mhz Ram (I know old school and prob Bottle-necking me)
750GB 7200rpm Harddrive
460W Power supply
Creative X-Fi Gamer Edition Sound Card
PYN GTX 550 Ti 1GB
Do I want a new System yes! But I couldn't pass up this deal got the Tower, 22" HDMI Monitor, Saitek Cyborg Keyboard, MX518 Gaming Mouse all for 200.00! So for the total of 289.00 Ive got a system that plays everything at max settings smooth enough for my tastes.
