Looking for advice on which card to buy for SLI I own a gtx 770 2gb, should I get a 1gb card?

I am looking to build a PC around my recent purchase of a Twin Frozr GTX770 and would like to use SLI. I don't know much about it and would like to get the most benefit out of the least cash. Any suggestions would help. Thanks!

  1. The only way to SLI a 770, is to get another 770.
  2. with the same among of ram.
  3. For sli you would need another 770 card. so i would see who has the best deal on a 770 2gb card and get it.

    Not true. You can SLI a 2gb card with a 4gb card, BUT you will only use one card's VRAM, so it doesn't make any sense to spend the extra money to do so. If you are using 3+ monitors, SLI with 4gb cards. If it is 2 or less displays, or at resolutions lower than 2000 (whatever it is, can't remember off hand), just SLI with 2gb cards.

    You mean it will use the least among from the 2, as each gpu will use it own vram.

    From geforce website, model and ram among have to be same. so it is not using just one card vram. how sli works http://www.geforce.com/whats-new/guides/introduction-to-sli-technology-guide#2

    That argument is irrelevant and wrong. It's not like the OP is going to sell off his 770 just to get a 4GB version for SLI. So only 2GB 770 SLI is relevant.
    Another thing is that the cards duplicate contents of memory and not use only one card's RAM. If the OP were to put a 1 GB 770 in there(which doesn't really exist, just for the sake of argument), the total memory reduces to 1GB. Your explanation suggests otherwise.

    Nvidia requires both cards to have the same amount of VRAM. However, they do offer a tool to neuter one card to be the same as the one with less VRAM. You'll need to find Coolbits to do this, but it will still require the same GPU on both cards (two 770).
