Hi guys ..first lets make sure about which one is better & more usable PCI 2.1 cards or 2.0 ? because 5850 has both . which one i should buy ...& second Question is that GA P31 DS3L is little old mobo ...does it support PCI 2.1 CARDS Fully or it will LIMIT these CARDS ?

if you have a pcie 1.0 slot, i'd go with the 2.0 over the 2.1

Yes they do, but only if the manufacterer of the Motherboard supplies a BIOS update that includes 2.1 support.

To be safe just go with a 2.0 card.

OK ...Some Brands of 5850 are 2.0 but some of them are 2.1 ..are 2.1 cards more powerfull than 2.0 ?? i have got 1 PCI slot ..but 5850 need 2 SLOTS ...so any way will my mobo LIMIT this beauty even if i get 2.0 one of it ?

your board will be able to accomidate the 5850 and you will only see a very slight drop in performance

Will THAT Slight Drop of performance effect on the GAMES too ..i mean real 5850 gives 100% ...can you say with % ..how much Perfomance Drop would be with % ?? & will Corsair 650 TX & 4 GB DDR 2 800 MHZ ram ... & Q9400 Quad Core CPU ..FIX this little PROBLEM . ?

yes, it will be only about a 1-5% drop

this is a limitation of your board, not the rest of your componenets

you should have nothing to worry about

Oh thanks ... But anyway ... if i had choose bettween 5850 PCI 2.1 & PCI 2.0
which should i get to experience more PERFORMANCE ? & is it truth that GIGABYTE brand has more core clock than other cards like MSI or XFX or HIS or...
Recomand me Best brand from { CLUB , MSI , His , Giga , XFX }

all brands have the same basic speeds, the only difference is the overclocking ability and cooling options

the best brands are probably xfx, asus, sapphire and gigabyte IMO

if you are going to upgrade your board, look for one with a PCIe 2.0 or 2.1 x16 slot

then you'll have nothing to worry about (in terms of performance drops)

OK .. what do u think about P45-USB3 ... is it 2.0 or 2.1 ...? if it is not so Recomand me a cheap one that already has PCI 2.0 or 2.1 ..thanks
August 22, 2010 9:08:50 PM

looks like it is 2.0, which is good.

you should be fine with that board, but you reallly don't need a new one. PCIe 1.0 x16 is fine. you'll hardly see any performance drop. i'd stick with your current board for now...
