9800gt sli with p5n-d 750i mobo
4850 cf with p5q p45 mobo
Either option, I'll sli/cf a year or 2 from now (sooner with 9800gt)
But which will perform better 980gt sli 16x or 4850 cf 8x?

4850 8x

by a lot

but i'd get an x48 as the p45 is just a board with a lot of features which is great for overclocking... but the x48 is the real crossfire king

The difference between 16x and 8x is negligible now... in the future with future cards it probably won't be though

Yea, but x48 are expensive, can't find one below $200.
So that 16x 9800gt will be a better performer in the future compared to 8x 4850?

look at it this way, the 9800gt is showing its age just now so what make's you think it will cope in a year or two. i would go with the p45 chipset it runs cooler than nvidia's and its pretty solid

BTW you can overclock the nuts of the p45 so i dont know where you get ur information

you'll probably be able to find a better card by than.. im sure in one year, instead of getting a second 4850, one 6850[maybe] will probably be better

Never heard of 6850 and I gues a single 4850 will last at least 3 yrs for my standards
Well as of now final pc specs:
e8400 with after-market cooler to 3.4ghz
sapphire 4850 dual slot cooling
p45 pq pro http://www.newegg.com/Product/Product.aspx?Item=N82E168...
p182 case
750tx psu
ddr2 pc6400 4-4-4-12 ram

get a p45 with pci 2.0...

and don't go crossfire

as eklipz sad, there will be a better card out... for about the same price...

Dual card solutions are a waste of money... unless your being sponsored like liquid... and gets lots of equipment free of charge... than dual and even triple card solutions are great :D 

EDIT: what he means by 6850 is the mid range card TWO generations after the 4850

am i right eklipz?

^^ all p45's are pci2.0

If you actually look at any other game provided in the tweaktown example other than crysis, crossfire doesn't even kick on on the p45 they use (the benchmarks are the same as a single card), if you look at say 3d mark vantage or UTIII the differences are minor at most and in some situations (even in tweaktown's benchmarks) the p5q comes out on top. Only if you game at the highest resilutions (ie. 2500 1600) will a 4850 get bottlenecked much. Remeber PCIe2.0 8x is the same as PCIe1.0 16x. I have 4850 cf on a p5q deluxe and have no resentment for my decision. also the P45 is a much better chipset and you will be able to do so much more with it. (does p5n 750 even have raid support?) And since the op will have just a single card for a while he should get a 4850 which is a much better card. You will only need all 16lanes of PCI2.0 if you get a faster ati card like a 4870 or a 4870x2 in cf which would show significant bottleneck. Or if all you play is crisis.

9800gt sli. Most people underestimate how much pcie2.0x8 will bottleneck cf in graphical intensive games at high settings.

You really need x38/48 for cf. Or just go for single card.

you are wrong again dagger the p45 in crossfire preforms better that the x38 but not the x48, cant remember the link but its true
