I have already pre-ordered the collectos edition for Rift, am well looking forward to it, just wondering if i could possibly upgrade my computer for a better experience. My current spec is: AMD Phenom 9850 Quad-core processor, 6gb of ram (formerly 8gb, but one went kaput), 1gb NVIDIA Gefore 9500 GT SLI.

In game i run about 15 fps on my own, and obviously a little less in the middle of a rift, this is on medium quality presets.

My thought is to either upgrade my graphics, either with another 9500 GT on the SLI thing. Or a whole new card? or would it improve if i replace that missing 2gb of ram?

Any advice would be appreciated.
