If the graphics card has GDDR2 memory, is it compatible with a Pentium 4 that uses DDR memory? Thanks.
yes as the videocard ram is seperate from motherboard ram. there are even cards with ddr3 ram on them.
yes of course vga memory is separate from system memory it has its own memory controler so it doesn't matter if you mobo is ddr1. you can use ddr2 or ddr3 vga memory too.!! hope i help
As said before it'll be compatible, but only if it's the right interface. For example you can't put a PCI express card in an AGP slot, so make sure you have the right sort. Specifically GDDR2 and GDDR3 are separate from DDR2 and DDR3. You can even get GPUs with GDDR4 on them now.
