Which? 2x 7600 sli or 1x7900?

gonna be a new system running AMD 4800X2 3-4GB RAM

Gaming machine.

well, did a google search for the above, seems unles you have money to burn
a single 7900 is better than two 7600.
any other comments?

Now are you beginning to see the hollow appeal of SLi / Crossfire? :-)

From all the reviews I've seen, 2 SLI mainstream cards don't
beat out a single highend card. ex. SLI 6600GT couldn't beat a single
6800GT/Ultra, and SLI 7600GT/GS can't beat a single7900GT/GTX. Doubt
it even beats a single 7800GS/GT/GTX.

Thank you all for replying.

Hi
I have a SLi machine with 2 x 7600GT cards. It absolutely thrashes my other
computer with the single 7800GT. The benchmarks I get with 3DMark 05 are
9975 and 5350 for 3DMark 06.
This would indicate that a single 7900Gt would not compete although I cannot
answer for a 7900GTX. 2 x7600GT's do not cost as much as 1x 7900GTX .
There was not a lot of difference between the 7600GT and the 7800GT when I
was running one card.
I am not defending Sli but just trying to put some actual experience into
the discussion. You would probably be better of with one 7900GTX if you can
afford one.

So how do you two computers compare when running *real games*? 3DMark is a
synthetic benchmark and shouldn't be relied upon as anything more.

3DMark will use the SLI if you have it. With apps which can't take
advantage of SLI you'll actually get marginally worse performance than if
you had only a single card of the same type (due to the SLI overhead). And
are both your computers otherwise identical?

Hi
The 7800GT machine is an AMD 64 3200+ with an ECS motherboard. The Sli
machine is AMD 3800 X2 with an ECS Extreme Sli motherboard. Not exactly a
level playing field I grant you.
With regard to performance it depends on the game. Sometimes the Sli setup
has been problematic on certain games. this I put down largely to the older
LCD monitor not being able to keep up with the high frame rate. I have
swapped the monitors around and most of the problems have dissapeared.
Generally I can play with a higher screen resolution and anti aliasing
switched on with the Sli system although there can be unexpected glitches.
The 7800GT works smoothly at a lower resolution with no anti aliasing.
My original plan was a Sli setup with two 7800Gt's but I found that I could
not get an identical card, such is the pace of change in the graphics
market.
Another advantage of the 7600 GT setup is its relatively small size. The
7800GT is a massive card that requires its own power connector. The 7600
setup needs no extra power connectors.
The reason I have two macines is that there are so many kids in the house
who want to use them. I have to have two to have any chance of spending any
time on one.

3DMark05 and 06 will both utilise both cores during their CPU tests, which
will boost the overall score even further, so not all the difference is due
to graphics card performance.
