Hi,
I am wondering what I will get better performance out of:
an 8800gtx 768mb or 2 SLI'ed 8800gts's 320mb.

I would even consider a similarly priced top line ATI card or a Crossfire setup.

The system this would be going into is a c2d e6600, 2gb ram.

It will be used primarily for gaming.
Thanks.

well, in current games the 8800 gts 320 sli'd would in more than 50% of cases outperform the 8800GTX. BUT...and this is a big BUT, even with sli, you will be limited to just 320 megs or memory (memory does not add up in sli, you still have the same memory).

sooo future games that require more memory may not run as well as the 8800gtx which has 768 megs. Also if you plan on running future games on much higher resolutions, then again the 768 megs of the gtx would be much better suited for that sorta requirements

so what about 2 8800gts with 640mb?
2 of these work out to about 1.5 times the price of 1 8800gtx.

Tru enough.But again as my friend has told you,the memory may be an issue later on.I recommend getting 1 8800GTX for now,and buy another one a month or two down the road.That way you'll have great graghics power now,and even better in a couple months.That's the only way I'll manage it myself.Buying one GTX is definately the better way to go.Until later.Goodluck.

Go with 1 8800GTX. 2 8800GTS's in SLi might be able to outperform it, but going with just one card enables you to drop in another later. SLi isn't worth it unless you are using the absolute fastest card out there (although the 8800Ultra is an exception to that rule).

well, from what i've read and experienced, crossfire fares very very well on the new cards against the 8 series cards' sli

I have pretty much decided to buy a top of the line single card, now the decision is between nvidia and ati.
How different is crossfire technology from sli? IE: can a motherboard support either crossfire or sli? Or is buying a mobo pretty much a commitment to one or the other?

The reason I ask is because many motherboards today list SLI ready or Crossfire ready in their specs, does that mean that the other technology is unavailable on that particular motherboard?

Correct, a board can support either SLI or Crossfire, but not both(although I have heard of SLI running on Crossfire boards with a driver hack).

EDIT: Here's that driver hack I was talking about.

Another question is, how power hungry is the 8800gtx?
I really like the Corsair HX620W PSU for the stable voltages on all of its rails, however I am not so sure it will be able to power a system with c2d e6600, 3 HDs 2 optical drives and an 8800gtx. Any opinions?
June 25, 2007 6:46:50 PM

Yeah, that PSU will be fine, without going into too much detail. Actually even the Corsair 520 watt would be enough, due to the high quality parts and strength of the 12-volt rail, but that would be pushing it.

EDIT: if you are planning to SLI in the future though, I would get a stronger PSU ~750 watt or so.

I am planning on purchasing another 8800gtx further down the road for SLI, I am thinking of going with this silverstone psu:

havent read any in-depth reviews on it, but have heard great things about the Silverstone OP series, what do you think?

edit: reading some unfortunate stories on the newegg's customer reviews.
