9800gtx or 7800gtx

Specs: Windows XP
Im currently running 2x 6600gt's in sli but one is now decided to start overheating so i thought id upgrade to a 7800gtx but now im wondering if the 9800gtx would be a better deal as there isnt too much difference in price! What do you all recommend as im not a computer wiz but do enjoy owning a quality system.
Cheers
Dan.

You might want to look at power supplies too, 9800GTX+ needs separate 2 4 pin molex power connectors

It requires two 6-pin connectors, actually.

Since there's little difference in price, grab the 9800GTX. It's around 3x faster than the 7800GTX in raw speed, and more capable (DirectX 10, the ability to run CUDA applications, HD video bitstream decoding, etc.).

The 9800GTX+ needs 2 6 pin molex connectors. There is an adapter supplied for a regular molex connector to give you 1 but you also need a "native" one from your PSU. I had to upgrade my PSU to get one!

It depends if you are running a older single core processor then the processor will bottleneck the 9800gtx.

im running an asus a8n32 sli deluxe motherboard and a 939 pin 2x core 4800+ cpu ive also only just upgraded my psu to a win power model: as-p700l. will these be good enough to not bottle neck the graphics card? Also what exactly does a molex connecter look like? in the replies no1 and no3 one person says i need 4pin and the other suggests 6 pin which do i need?
Thanks for all your help
Dan.

Hi,

I mentioned the 4 pin molex. I made a mistake, I should have said 6 pin. This is what they look like:

this is the kind of adapter that comes with the card so you can convert 2 standard molex to a 6 pin. Unfortunately, it needs 2 x 6 pin molexes so you need another one on your PSU. Sorry for the confusion

oh i see!
Just looked in my computer and have only one spare 4 pin and one spare 6 pin! What would be the best graphic card i could hope for with this limitation? There is a 6 pin that powers my mother board, this must power both my 6600gt's as they only need the power from the pcie slots. Is this correct?
Thanks again
Dan

what is the best graphics card that only needs 1 6 pin molex as i dont want to upgrade my whole system and just want to notice a slight difference (improvement) on my sli 6600gt's as when i do replace a computer component i like the idea of improving it as a whole.
