Why you should get 2 SLI 7800GT's

post #1 of 9
Thread Starter 
Interesting study on Tom's Hardware

http://www.tomshardware.com/2005/12/...ia/page38.html

Using the Asus 7800GT and the Asus 7800GTX (256 MB) as examples (there are other cards on the study that back this up but apples to apples eh?)

3DMark05: Asus 7800GTX 6524
Asus 7800GT SLI (x2) 10886

(EVGA 7800GTX 512 MB 7983)

66% Faster

FEAR: 7800GTX 37 FPS
7800GT SLI (x2) 47 FPS

(EVGA 7800GTX 512MB 47 FPS)


27% Faster

Quake 4 7800GTX 75 FPS
7800GT SLI (x2) 102 FPS

(EVGA 7800GTX 512MB 110 FPS)


34% Faster

By neweggs pricing, a 7800GT is $760 US (2x$380 US) and a 7800GT is $480 US. Two 7800GT's are 58% more expensive than a single GTX. The 512 MB GTX are in at $750.

So basically, the two 7800 GT's are faster and more expensive than a single 7800gtx 256 MB and on par with a 512 MB 7800GTX for $10 difference. Also its much more likely that the 7800GT's will continue to drop in price whereas the 7800GTX 512 being a specialty item, will be in higher price points for some time to come. The nice thing about the 7800GT's as well is that with the new drivers you can mix and match any 7800GT's. Also you can buy only one at a time and waiting till the prices drop on a second card.

Actually 2 GT's can be easily had for $600, $120 more than a standard GTX and exactly equal to the eVGA GTX KO (fastest clocked GTX OTB)...and you get mroe performance with the GT's in SLI

I only sourced newegg but you are right, 7800GT's can be found much cheaper and as such make the equation stronger. There are a few members of this forum that insist that SLI is not a signifigant technology and yet studies like the one on Tom's Hardware come out and prove them wrong. Also interesting is the the same people that insist that SLI is not a valid technology are usually the ones that insist that benchmark programs like 3dmark aren't an accurate reflection of game increases (And SLI tends to slaughter benches easily). Thats why this particular study was nice because it used 3 current pc titles with results to back up its claims.

In all the comaprison I've seen with SLI, the GT in SLI is right behind the GTX in SLI becasue you arent going to notice FPS drop from 120 to 110, until you get to 1600x1200 w/ AA and AF max, my native res is 1280x1024 so in those settings the GTX is favorable by a decent margin bt not worth the extra $300 I could spend on memory.

The 6800GT is the best bang for the buck in SLI, IMO but for $600 the 7800GT is not that far off


Also, in some of those benchmarks it even states that the gmaes that do the best are the ones that are optimized in SLI, yeah older games arent going to make much difference with 2 cards but newer games like BF2, CoD2, F.E.A.R. were optimized for SLI and the results are incredible

BTW...I got #1 of 2 7800GT's today..can't wait til the next one comes and christmas

What brand, I am expecting the asus E7800GT next week (1 of two to replace my 6600GT SLI) You'll really like the 3700 and the premium asus I had that board up till a week ago when I upgraded to the asus a8n32 (the permium is in rig 2 in my house)

it's in my sig, but as of now Newegg is out of the CO's so I might have to go elsewhere or get a vanilla one, and put a cooler on it to get it at 470...then later upgrade the other cooler to put it further

6800GT's prices are inflated, and 2 of them cost as much as a 7800GTX.. And a GTX is better. And even if you talk 6800GS, the 7800GTX is a better choice.

I have Zalman VF-700's on my 6600GT's which I will be moving to my 7800GT's (the stock coolers can go back on the 6600GT's. They are going in my kids computer and it won't be OC'd). The Zalmans make a huge difference on the 6600GT's. It will be interesting to see what they will do on the 7800's.

I would get something SLi but I don't have enough money. I'll maybe have enough money left for one 6800 and some new memory for my computer after Christmas. And that's pushing it.
