Does it have a 3.0 pci express slot?

I have one of these and the graphics card I use requires PCI Express 3.0 so I guess the answer's yes. It's a VisionTek Radeon HD 7750 SFF (Mfr#900549) which I chose because Dell recommended it. You can go to Dell.com and see what they suggest to get an idea of what you can add.

Slots: 1x PCI-Express 3.0 x16 Slot, 1x PCI-Express 2.0 x16 Slot (runs at x4), 2x PCI-Express 2.0 x1 Slots, 2 x PCI slots

Yes. This card is a standard PCI card, every pc in existence has at least one pci port including yours.

Yes it does, and whare can i get a cheep PCI Express or PCI VGA card to match this board

We are possibly dealing with compatibility, I inserted this card in the MSI LGA 1155 Intel mainboard H61M-P31, it will accept both PCI express 3.0 X 16 & PCI express 2.0 X 16 slot. I had no problems.............................

Your machine will need a pci-e 3.0 port that is free. I dont know about that machine in particular, but if it wqs made in the past five years or so it should have one.

I haven't actually opened the box. But I have the mini tower and I believe there are both PCI AND PCI express expansion slots. I can only refer you to the dell specifications. They are here http://search.dell.com/results.aspx?c=us&l=en&s=gen&cat=sup&k=Dell+OptiPlex+755+Core+2&rpp=12&p=1&subcat=ddc&rf=all&nk=f&ira=False&~srd=False&ipsys=False&advsrch=False

The card performs at PCIe 2.0 speeds only, but it will work in slots that support PCIe 2.0 and 3.0 (x8 or x16)

Yes sure. You just have to check your motherboard has a PCI-Express interface.

Yes. The PCIe 3.0 spec is backwards compatible, however there may be some minimal performance loss over a Gen 3 slot.

No, it only fits a regular PCI slot... Very nice card, and certainly worth the money. I should know. I've got one in my Windows 7 64 bit system. Tremendous card for the money.

PCI Express 3.0 x16. Yes. Great card for money. My computer runs like a dream.

The card is a PCI-e 3.0, but like all PCIe 3.0 GPUs, it is compatible with a 2.0 slot on a motherboard. You just don't get the advantage of the faster speeds offered by 3.0

Yes, pci-e 3.0 is backwards compatible to pci-e 1.0, so a pci-e 3.0 video card will work in any pci-e slot. The only caveat is that it will only negotiate the highest bandwidth that the motherboard will support, so a pci-e 3.0 card will not run at 3.0 bandwidth in a 1.0 slot.

It would work. Buy PCI express 3.0 if you can afford it. I don't have 3.0 however and the card still screams.

PCIe 3.0 slots only offer more bandwidth for your card to use, so in most everyday usage you wouldn't even see a performance increase with 3.0. So, no, using a 2.0 slot with a 3.0 card will NOT bottleneck your performance.

I got an email from their techincal support that this does NOT have an open PCI slot in it. :(
