I have one 8800 GTS 512 and I want to upgrade.Is another 8800 GTS 512 a good option?

If you have an SLi capable motherboard and play at high resolution (1680x1050 or 1600x1200 and up) yes. It is also important to know your other hardware and what games you play as these factors will determine how well a multi-card setup will perform for you.

Other than the SLI capable Motherboard, Make sure your powersupply can handle the additional load.

Its nice man, get RivaTuner and overclock it too and you will be in graphics heaven. Havent tried Crysis yet, but COD4 is silky smooth on my 22". I just started Far Cry and I dont know if its supposed to be a load on cards or not, but that looks awesome as well with all settings to the max. With all the jungle trees and stuff it looks great.

Sucks power though and they get hot if you dont turn up the fan speeds.

What kind of motherboard, PSU and case do you have?

I have a Asus P5N-D with 2 PCi-E 16X 2.0 so yes it supports SLi.But I don't know about my PSU because I have only 31A an the +12v rail. I think it should work but at the limit . I have only 1 HDD ,1DvD rom and 2 GB ram and an E8400.

2 8800 GTs 512 using 217 watts. 31A= 372 watts right?

I think you'll be fine. You are sure about the 31A on the 12V rail, right? That is, we're not talking about 16A on rail 1 and 15A on rail 2, but 31A combined? What model is the PSU?

Heya,

Absolutely. The 8800 series in SLI still among the top end performers.

Very best,

Yep, it'll outperform 4870/gtx260 and gtx280 across the board.

Yep it seems to be the done thing at the moment, In fact anyone with a 8800 G92 card would really be missing a trick if they didnt go the dual gpu route at the price point the cards are at now.

mactronix

Not everyone has the sli motherboard it needs.

Going SLi with the 8800 GTS would make a pretty good upgrade, especially with the prices. The only thing is, I hope you have a good brand PSU. If you constantly push your PSU to it's limits you will shorten it's lifespan.

while everyone might not have a board capable of SLI physical slot wise, there is always hacked drivers for non nvidia chipsets if your willing to ask around, i agree with mactronix. The price/performance on sli'd 8800's compared to 200's/4800 couldn't be much nicer.

Hacked drivers? Lol, can I ask you where they are?

This is so crazy, people installing hacked drivers and then blaming nVidia or Microsoft for crashes. Plus, they might have spyware...
