Get an aftermarket cooler and crank that Q6600 to 3.2-3.4ghz instead
Alternatively, you'd be better served if you sold your card for $120, purchased a 4870 for $230 or GTX260 for $210. Either of those scenarios will provide a faster gaming performance than spending the same amount of $ on a P45 motherboard.

it is not negligible if you have 4870 CF; if you don't want to compromise, then the full 16x + 16x is what you want from x48/x38 as i am doing,
However, evidently the difference between 1.0 and 2.0 PCIe is not enough to upgrade even though the available bandwidth is evidently doubled
-i am testing this also as i go from p35 to x48
if you are looking for a new MB *anyway*, however, you might want to pick x48 or x38; x48 is ~$200 if you are keeping the current platform. i believe Nehalem's i7 lanches the end of November if you want the bleeding edge of technology - that means your wallet is also bleedin'
if you have a single GPU it probably makes sense to keep your current MB; i will know for sure pretty soon. i am backing up all my data right now to do clean installs so i can compare MB platform differences. All my benches with Cat 8.8 are completely done, so i already have the relative performances of 4870x2, 280GTX, 4870/512, 8800GTX and 2900xt established at 16x10 and 19x12.
These new benches with Cat 8.9 will specifically show P35 MB's PCIe limitations - if any - with the higher performing GPUs including it's 1.0 PCIe interface vs x48's 2.0 and P35's 4x PCIe 2nd CF slot vs x48's full 16x bandwidth. It is an ongoing project and i should have that phase done next week.

I'm pretty sure I've seen benchmarks around that show a performance hit with SLI/xfire in PCIE 1.0 8x/8x. I think it was also concluded that a 4870 x2 would be bottlenecked by a 16x PCIE 1.0 link, and needs PCIE 2.0.

I never mentioned anything with regard to a CF setup. I am just responding to OP's original question which considers his setup (1 graphics card) only.

There is no point in spending $200 for 1% performance gain unless there is a need for a dual graphics card setup.
It'd be interesting to see if 16x bottlenecks 4870 x2.

i know you didn't mention CF - at all; i just wanted to clarify the need for it - with CF. And it is not "$200 more" for a x38 MB over a P45

i am reformatting now and will test 1.0 vs 2.0, shortly
--p35's 1.0 vs x48's 2.0 16x PCIe slot; as well as the 2nd 4x PCIe slot vs the 16x provided by x48
there is only one review i am aware of so far, most have been done comparing P45 vs x38/x48 - i want to explore the older MBs a lot of us got last year
so what were your results?
