buying a new video card... please help?

ok. so i baught myself a new video card so i could play final fantasy XI and doom3... well, it turns out that while the card is BIG enough (256 mb) it isn't near fast enough (200 mhz)

anyway, i've been lookin around on pricewatch to see if i can find some faster cards. the only problem is, i'm not enTIRELY sure on what all the statistics mean for each card...

here are the stats given for one of the cards i'm viewing. i would really appreciate it if someone could tell me what each thing does.

PC5750Q,
NVIDIA GeForce PCX 5750 Chipset,
128bit
256MB DDR,
PCIe x16,
Ramdac 400MHz,
Engine 425MHz,
Max Res 2048*1536*32bpp,
TVOUT, DVI, GamePack


thanks again.

This is a PCI Xpress card right? I don't quite understand

& I really hate to ask the obvious stupid questions, but here goes.....You are using this on a PCI Xpress Motherboard right?

c'mon. all i need to know is what these two things are:

128 bit and 256 mb ddr
