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

Get rid of it. You want to stick with dual channel RAM (dual channel>>>>>>>>single channel).

If you want/need to upgrade your RAM, either:
  • Install another 2x2GB kit.
  • Replace your current kit with a 2x4GB kit.

The 6990 stock is just a tad slower than the crossfire 6970, barely anything IMO
my mobo has 4 pcie slots, i'm thinking of getting 2x6970 and then stop the GPU upgrading on this pc or get one 6990 now, and add another(maybe) in a year or so.

would there be an significant difference to a single 6990 if i add another one(and provided that I oc my cpu even more)?

6990 at unlocked mode runs the same as 6970s but is alot hotter and is very loud.

Just stick with what you got, anything more will bottleneck. Besides, what do you need it for unless your running 2560x1600 or triple displys?

You may want to look into upgrading your PSU sometime in the future, too. Rosewills are generally pretty mediocre, and yours is nothing stellar.

You're fine at the moment, but if you plan on upgrading to a pair of cards that draw a lot of power (such as the 6990) upgrading would be a good idea.

You're board can handle 2 easy, but your cpu will bottleneck.

IMO, if you want to see more performance, OC your CPU first. For the money, a 6990 is enough. Adding another 6970 will increase it some and might be cheaper later on and make it worth it, but adding two 6990s is really a serious overkill unless your running multiple monitors and higher resolutions. Plus I think your CPU will bottle neck seriously.
