Graphics Advice?

post #1 of 9
Thread Starter 
I have one 8800gtx, do I get another and SLI them and if so will a XFX 8800gtx work with an XFX extreme 8800gtx, or do I get a 9800GX2.

I am only running at 1440x900 at the moment, however I will be upgrading to a 30†screen this year!

you need to get a matched card for sli i.e the same card you have now mixing cards with different speeds etc can and will cause issues!

Tough call.... first, price comparison (note that you WILL need a new mobo if you want SLI).

1) add an 8800GTX
8800GTX $359.99
Motherboard: $149.99

2) 9800GX2: $499.99

That's just about a tie. (based on the cheapest solution I'd recommend).

In terms of performance, it'll be darn close.

Also, there is a bunch of new cards coming out soon, and since you won't get the big screen until the end of the year, I'll be wise to wait. SLI won't matter much on your current monitor.

I'm pretty sure they will work together, the faster card just runs at the same speed as the other card

yeah, they'll work together... just at the speed of the slowest card in the pair.

Again, I'd not upgrade now. There are new, more powerful, cards coming soon, and you might want to wait until you actually buy the 30" screen.

I agree, match the cards, (not manufacturers) only need same type n speeds. Might want to wait for the 9900 x2 cards, supposed to be the sweetness.

I mixed cards from different speeds and vendors and I don't have any problems. All I had to do was flash both to the same BIOS. Don't even need Rivatuner anymore since they boot up at OC'ed speeds.

totally agree but i have seen my mates sli set up with a standerd 8800gtx and an ultra he lost performance and kept having graphics errors and glitches because the cards were not matched :-/

okay thanks for the information, unfortunately I cannot wait as this is an insurance claim!

I realize i will need a new board, I was looking at this

I was also looking at this memory

Also will a 620w PSU be okay for the SLI setup.

I think I will go for another 8800gtx, will the new cards be a massive leap forward in development, I mean will they make 8800gtx obsolete?
