Hi just wondering what graphics card i can put in my dell dimension 5000 bought in 2005 psu is 305 i have a Gforce nvidia 6800 256mb and wanted to upgrade to 1 gb for about £70 pound i have found a few cards but not sure if they will work the cards are Gigabyte ATI Radeon HD 4650 1GB GDDR2 PCIExpress DVI OC or Sapphire RADEON HD 4670, (1 GB) PCI Express Video Card or AXLE nVidia GeForce 9500 GT 1024MB 1024MB DDR2 9500GT PCI-E VGA / Digital Visual I..., (1 GB) PCI Video Card these are just a few many thanks for any help
why a 1GB card? in terms of performance, the ATI 4670 512 DDR3 will outperform an ATI 4670 1GB DDR2 card. in fact all of the cards you listed do not have the performance to take advantage of 1GB of ram and most come with slow DDR2 RAM.
i would personally look at one of these two cards.
ATI 4670 512mb DDR3 (budget)
ATI 5670 512mb DDR5 PCI-E 2.0 (solid)
