6990 vs 6970x2?

post #1 of 29
Thread Starter 
I read online that the performance for 6990 is actually lower than the 6970x2 but that the 6970 is a little more expensive and i could just add another 6990 a few years later.
I thought about either getting 2 of these

or 1 of these now, and maybe in a year get another one
http://www.newegg.com/Product/Produc...82E16814102927

what do people think, and can my mobo handle two 6990s

Stick to what you have as there is no games out there that even need x HD 5850. Tel me a game you have trouble running? Also you CPU will be a bottleneck for such GPU power and not see as much increase from what you have now.

There's really no real need for you to upgrade your GPU at the moment (you'd be better off investing in an SSD). If you decide to upgrade anyways, I'd go with the 6990.

On a side note, is that 2GB of RAM you added one 2GB DIMM or two 1GB DIMMs?

If you have a motherboard with only two PCI video slots, the 6990 + 6970 will trifire as 3 GPUs. If you're happy with only 2 cards, then the two 6970 are fine. For me, I want to watercool, so two 6970 waterblocks will be more than a single 6990 waterblock. It all depends on what you're setting up. The 6990 stock is just a tad slower than the crossfire 6970, barely anything IMO

I guess thats true also. but maybe if i overclock my cpu to somewhere around 4.2ghz(guess i'd have to change my heatsink)
