7800GTs in SLI

post #1 of 21
Thread Starter 
is it tru i will only see a performance difference if i run it in 1600x1200? Since my monitor supports up to 1280x1000 would it make sence ?? should i just stick with a single GTX??

dude one gtx all the way, dont buy two cards right now. cheaper and more future proof if there is such a thing.

i dont know if the screen size thing is totally true but it sounds roughly reasonable.

You will get higher framerates with AA and AF cranked up all the way. But yeah, you will see a huge difference in performance at any resoloution compared to your x700. You could also eventually upgrade your monitor to a monitor that supports 1600x1200. I would go for the SLI GTs.

About 10.
But that is with most current games. Your dual GTs will pwn a single GTX in UT2K7 and COD2, and all other current games written to take advantage of SLI. You will score a fair amount higher in benchmarks. But, you will need an AMD processor runing at 3GHz, and an Intel processor runing at 4.0GHz in order not to severly bottleneck the SLI cards.

im building a new pc actually, with a 4400+. I guess I will stick with the dual GTs then. How much on a +12v rail should I look for to run both of these?

Mine has 38A on Dual 12V rails, btu Im not going to run SLI until after my Bday

Anything 32A+ and get a SLI compatible PSU and preferribly dual rails, we'll see how this X-finity 600W does for $50, some say it's pretty good (retails for $100 but there's a $50 rebate good until tomorrow I think)

but if you can do it get 2 eVGA GT's cause when the prices of the GTX's drop you can do the step-up and pay the difference and have 2 GTX's I'm probably going to end up doing that when my 90days is almost up

seriously why pay $600 for two cards that will be outdated in a year when you can pay $450 for one card that will not be as outdated in a year and still good enough to play current games on high for at least 6 months?

also sli doesnt help at all in some games.

So why pay $750 for a 512 GTX or pay $500 for a decent GTX when it's going to be outdated in a year, why buy anything nwo if its going to be outdated in a year...seriosuly these are computers do you not know Moore's Law???? (doesnt toally reflect on GPU but of course something new and better will come out)

SLI wasnt a factor when it first came out because games weren't optimized for SLI, ALL of the new hit games that come out now are optimized for SLI.

Go read some benchmarks on GT SLI vs. GTX comparisons on 1280x960 and 1600x1200 and you'll see that SLI is the way to go if you have the money because $100 more dollars to get 30-40% more performance is worth it IMO

Splinter Cell:CT in 1260x1024
1 GTX= 74 FPS
2 GT SLI= 111 FPS

33% gain in SLI

w/ AA and AF
1 GTX = 60 FPS
2 GT SLI = 91 FPS

34% gain in SLI

Taken from here http://www.guru3d.com/article/Videocards/242/12/ and there are more benmarks for more games

Try 150+ Games if you're playing newer stuff and not Doom2 http://www.slizone.com/object/slizone2_game.html

No, all new hit games are not optimized for SLI. Where'd you gather that info? Here's some of the most popular new games and you can see that SLI is actually hindering performance in some of them....
