No, it doesn't.
PCI-e card cannot be used on the 4600 motherboard.
PCI, PCI-e, AGP
No, PCI Cards will not fit on PCI-E slots
Yes. PCI-E 2.0 is backwards-compatible.
No, the 8600 gt requires a PCI-E slot but the Dell only has a PCI slot. that graphics card will also be held back by the CPU so, even if it would work, it would not work to its full potential because the CPU would be able to keep up
I believe you have an integrated video display, it's hardwired to motherboard. Unless it has PCI-express specifically built on mobo I would say no. You can put PCI card assuming you have a free slot. cheers.
PCI express (commonly referred to as PCIe or PCI-e) have taken existing PCI technology and multiplied it. (1x, 4x, 8x, 16x) PCI-e typically has a 16x or 8x multiplier compared to the original PCI transfer rates.
Any Video card on the market as long as you got a Decent Power Supply and an PCI-E X16 slot on the motherboard.
yes
No. You will need to replace your motherboard to get PCI-E.
PCI-e, Most deffinatly. PCI-e 2.0 is the current technology and should be the one you are looking for.
