Need a board with PCIe (2.0 or 2.1) for GTX 460?

[thewalrus34]

I've decided to by a GTX 460 as an upgrade from my 8800 GTS 640mb, but my current motherboard is an Abit Fatal1ty FP-IN9 SLI (Specs should be there)

I don't want to upgrade everything at once, but I may have to.
Current Specs:
Operating System
MS Windows 7 Ultimate 64-bit
CPU
Intel Core 2 Extreme QX6700 @ 2.66GHz 50 °C
Kentsfield 65nm Technology
RAM
8.0GB Dual-Channel DDR2 @ 399MHz (5-5-5-15)
Motherboard
http://www.abit.com.tw/ FP-IN9 SLI(C55-MCP51) (Socket 775)
Graphics
L226W @ 1680x1050
640MB GeForce 8800 GTS
Hard Drives
488GB Seagate ST350063 0AS SCSI Disk Device (SCSI)

My main question is do I need PCIe 2.0 or 2.1 to fully enjoy my new card, and would I not be future proof in getting another board with an intel 775 Socket as well as DDR2?

You will see no diference between a PCI-e 1.0 board vs a 2.0 board while using a GTX 460. You would not have an issue unless you decided to go with 2 of those cards in SLI and even there the difference may be so subtle you may not be able to perceive it.

You will be fine with your original motherboard. If you want a new one that is a different story, but bandwidth will not be a bottleneck on a single card solution.

Thanks, I didn't really want to buy an entirely new PC

Well, what kind of a performance drop would there be with SLI GTX 460's on a PCI-e 1.0 board? I was going to buy a GTX 460, I've got a P5N32-E SLI Plus and might want to pick up a second 460 at some point. The board has SLI support with two PCI-e 1.0 x16 slots (so I guess like two x8 slots on current hardware?). Is there a huge difference in the way SLI works on the 650i-period boards and current hardware so that two GTX 460 cards wouldn't scale properly on this motherboard?

Actually, it looks like it would be a pretty bad idea to buy anything more than a single 460 (or other new card) on my current system. The platform and a Core 2 Duo around 3.0 Ghz seem to bog down current dual-card setups by quite a bit.
