 Hello all I've never posted before but I currently am in a situation where I am not sure what to do. I have a BFG 8800 GTS 640 OC2 video card and to play in SLI I am not sure what second card to get. It would be nice to have a matched set purely for asthetic reasons but realistically I guess it does not matter. As a second question what kind of temperatures are normal for an 8800 under load/idle.

I don't have any experience with sli so while I want to give you an answer, I don't want to give you any wrong info. As for temps low-mid 60s clecius is considered noraml/safe, but below 60 closer to 50 would be ideal... loads temps can approach and even pass 80c a bit and still be considered normal/safe, but ideally under 70 would be best.

Use a utility like ati tool or riva tuner to check your temps and adjust the card's fan speed if needed.... I have an 8800ultra and have the fan locked at 100%, under heavy load the card never breaks out of the 60s.

you can only run SLI with the same cards, so you will need another 8800gts to run SLI, running a GTS and GT will not work.

 As for the second question, my 8800gt is OCed by 50mhz, runs low 50s idle, 75 load.  I have the single slot card, the dual slot card runs much cooler

You will have to SLI with the same card as vicaphit said. Unfortunately, the 8800 GTS 640 is quite pricey for the performance. Dual 8800GTS 640's can offer good performance, but when compared to a 8800GT sli setup, they can offer similar or lress performance depending on the title. But it wouldn't really be worth dumping that much into dual 8800 GT's. Which 8800 GTS would you get if you wanted to SLI? I see two on newegg, one is 299.99, the other is 419.99. If you could, try selling your card on ebay and pick up two 8800 GT's...They take less power, and offer better performance. Nearly matching or surpassing dual 8800 GTX's in SLI. Otherwise you may as well nab an additional 8800 GTS 640...But if that 8800 GTS 640 is indeed above 299.99, then I wouldn't recommend it...better to just sell your card and pick up dual 8800 GT's.

If you do get another 8800gts, make sure you get the G89 core, not the G92 core, the card you have will not work with the GTS 512MB version because it has a different core.
