It's a very viable option against the 4870 512.
I've compared findings from 3 review sites, and I gotta say, the 4870 512MB still has a leg up on even the GTS 250 1GB when strictly gaming.
According to Anandtech, the GTS 250
1GB never breaks 30 frames in FC2. The 4870 512MB does. It only beat it @ 2560x1600, where both cards give slideshows - amounting to no benefit.
According to Guru3D, the GTS 250
2GB breaks the 30 f/s mark by 1 frame and only at 1680x1050 in FC2.
Tech Report is the only review site I've seen where the GTS 250 1GB gets over 30 frames in FC2 and when it did, the 4870 512MB beat it. Granted, it does beat the 4870 512MB at higher resolutions, but if you still can't play what's the point?
In Fallout 3, Anandtech showed it beating the 4870 512MB @ 2560x1600 by 4.5 frames. The GTS 250 1GB was over 30, the 4870 512MB was not. All resolutions prior to that the 4870 512MB had a substantial lead.
However, Guru3D showed the 2GB version being unplayable @ 2560x1600, and when it was playable at 1920x1200, the 4850 512MB beat it.
Again, Tech Report showed both the 4870 512MB and the GTS 250 1GB being playable @ 2560x1600. The GTS 250 1GB beat the 4870 512MB, especially in minimum frames. In fact, their Fallout 3 minimum frames were better than Anandtech's average (or maximum, which ever Anandtech reports...they never say *hint, hint*).
In both games, tech report showed higher framerates for both cards, indicating they probably weren't in the most stressful scenarios in said games.
All things considered, the 4870 512MB beats the GTS 250 1GB for a great majority of the time.
But, as mentioned, CUDA is nice, and beings how we've seen nVidia GPUs work as physics processors while running ATi GPUs in Windows 7 I think for the 1680x1050 gamer it's great. If one looking to putt by until the GTS 250 can't handle things at their resolution, they have a card that does good now and will still have uses even when they get a new GPU.
