You have a 480 watt power supply (should be good enough, but be certain it can handle any new GPU you choose to purchase one).
You have PCI E x 16 (great, all that is needed, but be sure that you have room for your card some of them, but not all, actually take up 2 slots)
Vista may not recognize over a certain amount of RAM (if you upgrade from 2 gig, I am not certain of the maximum w/ Vista*)
*Please verify or check, as I am not certain.
As a result of reading through many discussions, it appears that DDR5, over DDR3 RAM on your GPU makes a distinguishable difference in performance.
Hummmm... Mostly correct but with some caveats:
1) Although the PSU claims to give 480 watts, it's old and not performing as a new one any more. More important, it most likely doesn't support modern video card, i.e. it lacks the plugs needed. Y-cables might work but they also might drive the PSU past its limits.
2) The two slot requirement for a video card isn't the only problem. Many cards are so long that they don't fit in between the back plate and hdd cradle.
3) About Vista's capability to handle memory: It doesn't say 64 bit anywhere, so it's 32 bit.
Any 32 bit operating system can only handle 4 GB at the maximum and even that isn't fully usable. The key word is bit depth and from there on it's purely mathematics.
4) Yes, GDDR5 is
much faster than DDR3. It's designed for
Graphics... The techies talk about buses, but for me a bus is a multi person car. My explanation for ordinary people is, that if the data were like water, a 3/4" hose will fill your bucket much faster than a 1/4" hose with the same pressure level.
@800nate800:
yeah but instead of upgrading this thing. i just need something new
You're absolutely right. The only thing you might want to do just for fun, is to install a video card if you can get it for free. A card without extra power inputs would be the safest choice. But before starting to plan this route any further, check that there actually is a pci-e 16x slot on the motherboard! I've seen some e-Machines having just two rows of solder spots instead.
