i've seen so many benchmarks etc. about dual x8 vs dual x16 and i've gotten so many different results.
i recently bought a 4850 and i'm using it on my pci-e 1.0 motherboard at the moment. (which is performing amazingly well. runs crysis very high and is totally playable.) gpu-z says i'm getting 67.2 GB/sec bandwidth. i don't have anything to compare that to though, is that good/bad?
i'm looking to get a 4850 crossfire setup and was looking at this board http://www.newegg.com/Product/Product.aspx?Item=N82E168...
which runs x8/x8. it's really cheap for a pci-e 2.0 board, but would it be worth it to get a board that runs x16/x16?
the x16/x16 ones i've seen are basically twice as much. is it worth it?
if i don't go the crossfire route would it even be worth it to buy a new motherboard to upgrade to pci-e 2.0?
$46 more (after shipping) buys you a K9A2 Platinum 790FX instead of the K9A2 790X. The 790FX version does x16+x16. If you're decided to buy that second video card then I think it's worth going with the FX.
LOL, and they say the HD 4850 is hot. My 8800GTX is at 72 degrees right now, and all I'm doing is surf the Web and watch Stargate on the second monitor. And your HD 4850 is way faster too... That 55nm technology is sure doing its job
There's a nice sale at the 750TX PSU at newegg, if you want.
I own the K9A2 790FX MB and its great. I got it for 149.00 at newegg in march. It has 4 PCIx 2.0 slots and its a good layout... for the most part. I cant get a PCIx sound card because the 1X slot is right next to the main 16x slot. My dual slot HD 3870 blocks it. But for the bandwidth My 3870 is 79.5 GB/s and I has the speed at 864/1242 up from 851/1143. Idle is at 33c and load running ATI tool is around 56c. But for the bandwidth my card has GDDR4 and not GDDR3 men. like the 4850.
but if my 4850s are gonna use the bandwidth then i wouldn't want to bottleneck them, especially if it's only $50 more. if the 4850s are designed for pci-e 2.0 then eventually games/drivers will require/support the extra bandwidth, correct?
also, aevm, i'm running my fan at 60%. i guess it's a bit noisy (hardly louder than my case fans, and i can't hear it while gaming whatsoever, but some people are picky about that.) when i got it the fan ran at 10% or 15% or something and was 70-90 degrees. and i didn't like it that hot. geckoars running his really low though, that's always nice.
