I have a Dell 9150 from 2006. I have just upgraded to windows 7 and need to find a graphics card that will match my PSU (375w) and has windows 7 drivers available. I have googled this for a few hours and didn't seem to find much info as it seems to be a bit old a dinosaur of a PC.
I would like to be able to play Call of Duty United Offensive (quake 3 engine) at full specs as I have a 1080p widescreen monitor. I have a Radeon x600 256mb at the moment but this is not an option for windows 7. I hope to find one that will play the game at 2048 x 1536 as the x600 only plays the game at 1280 x 1024. I also understand there will be limitations due to bottleneck issues and this will limit my choices and that is where I am coming unstuck with google but driver issues are a problem also.
I would really appreciate maybe two suggestions as I will have to try and find a second hand one on Ebay as funds are very limited. Thank you for your time.
