I currently have A Dell Dimension E520 which has a ATI Radeon X1300 graphics card in and a PSU of just 300W I think. I know the PSU will limit my options of graphic upgrades, but could anyone recommend a better card that would work with my system without changing the PSU?
That's not too bad at all. You should be able to throw a 2600XT on it which will give you a lot better performance in gaming and will HD video decoding onboard. It also has native HDMI which is a big plus.
Get an 3850. I have a E510 and thats want I am going to buy soon.
You will have to use a 4pin to pcie adapter but thats no problem. If you don't have any 4 pins then a 4pin to 2x 4pin y cable will do the trick.
Since this is an older post, can anyone tell me some of the newer cards that work on this machine? I also have an E520. The Dell rep said I could run a GeFord 9400 GT (PCI-e) with this? (Please bear with me, this is all pretty new for me!)
