Recently picked up a Dell GX280 that had a X300 Radeon 64mb card with DVI plug. Since I don't have an adapter, I took the card out and used the onboard video. Works fine, but I'm a little confused. The onboard video is listed as ATI 128 mb. The PCI-E card I took out is a 64 mb memory. Why would someone spend the money to put this in unless it was better than the onboard video? I'm sure there is something I don't know about allocation of system memory or something. Am I better off getting an adapter and using the Radeon card, or just stay with the onboard?

Hey there, The onboard graphics uses some of the system RAM as graphics RAM. this means that the actually computer may slow down as a result. I am not 100% sure but I think on board also uses more of the CPU and makes it slow down further as well.

You didn't mention how much RAM is currently in that Dell OptiPlex GX280.

It comes with only 256 - 512 MB pre-installed, but it supports up to 4096 MB(4 GB) for the desktop and mini-tower models and up to 2048 MB(2 GB) for the small form factor model.

Integrated graphics uses a portion of the computer's RAM for video memory, but a video card has its own video memory.

If that computer has a small amount of RAM, it would benefit more by having a video card with 64 MB of video memory than having integrated graphics that uses up to 128 MB of its RAM for video memory.

In case anyone cares.............
I got a vga adapter and put the Radeon back in and did some tests with PassMark. By the way, the computer has 1 gig physical memory. Comparing the results I came up with these numbers: 2D graphics, -20% 3D graphics, -30% system memory performance, +.3% overall system score, -11% These are the scores of the PCI express card compared to the onboard video. My daughter is playing Snoopy vs. Red Baron and can't really see any difference in that game. I'll put another couple gigs of system memory in and junk the X300 Radeon. Now I know.(y)

Basically as what was said before. The PCI Card will take away what the CPU and system memory have to do for Video Graphics Processing. They also have their own processor on top of their own individual RAM. So in turn it will help your system. A more intensive strain on the GPU (Grapics Processing Unit) would reveal the true nature of just what the video card is doing for you.
