Upgrading a 4870 ATI

post #1 of 3
Thread Starter 
Alright I am going to be buying a new computer, parts only and assembling them myself. I already have the list the only thing that keeps me from buying anything is my decision on a graphics card. I currently have a 4870 and it has started having some problems with more modern games like Crysis 2 and getting some freezing.

I don't know if I want to go either a duel GPU card like a GTX 590 or ATI's 6990.
or buy a single GTX 580 or some other ATI card, and upgrade a second and either crossfire or SLI them. I currently use two 1900x1200 res monitors, and in the future plan on getting a projector that can handle 1080p and 3d movies/games, but that may be a while. I do not plan on doing a Quad SLI with the 590's if I get them but If I get the 6990 can I hook it up to my 4870 with crossfire, and not have any problems for a tri GPU?

Thanks for the help.

1. There is NO WAY you can CF a 4870 with a 6990. You can only CF cards with the first 2 numbers identical (a 5870 will only CF with another 58xx, etc)

2. I would recommend buying 2 6950's and unlocking them, 6990 power for a fraction of the price.

3. Depending on how many PCI slots you have you could buy two 6990's or 4 6950/70s if your budget allows and you need that power.

For now, i would say buy a 6950 or 6970 and crossfire them whenever you are ready. But above 3x crossfire the gain is minimal and not worth a 4th card. This includes a quad setup using dual gpu cards.

Thanks railfain844, I am looking on newegg for a good 6970, and am having trouble on which brand to get. I have herd good things from XFX and Sapphire, but the cooling on the Gigabyte card looks like it will be very efficient. And if I plan on OCing the card should I buy the one with lower clock speeds and up it my self, or buy the one with higher clock speeds and up them farther?

Thanks again for the help, after researching the GTX brand more it seems that they are more hype than power with stuff like physx
