I've got an aging but still decent system with an 8800GT installed. However, the only way to get acceptable framerates out of ME1 is to lower the resolution to 1280x800, which is suboptimal on my 1600x1024 monitor. That gives me fps in the 25-30 range, which isn't great but is at least playable. The frustrating thing is that this same rig gives me 40-50 fps @ 1600x1024 in Dragon Age, which also looks better than ME1. I'm also looking to get my system ready for ME2. The most obvious bottleneck I can see is that my 8800GT only has 256MB of RAM. Could that explain the relatively low fps I'm getting from my card?

The drivers are at the right rev., but dxdiag says my DX9 files are pretty stale. I'll try upgrading those sometime tonight. You're probably right about the memory, but that leaves me with a dilemma. I have about $150 left over from Xmas, so I'm debating an upgrade. My monitor is ancient and has a big old pressure point on it, but it looks like I'm going to need the graphics card more. Most of the reviews I've read seem to indicate that there aren't very many cost effective upgrades for an 8800GT. Of course, bumping it up to 1GB might have a very positive effect.

Unfortunately, it appears that some software I use is not compatible with the 5xxx series. Since the software has been discontinued, it is unlikely it will ever be. However, it is possible for me to use the 48xx series. Which of those cards would you recommend? It looks like the 4850 and 4870 are in my price range. Would either of those, or even the 4830, be a significant upgrade from the 8800gt?
Based on that resolution, a GTX260 would get me a 50% improvement in FPS (above a 512MB 8800gt) for $164. The best 4870 I can find is $159, so I'll pay the extra $5 for slightly higher performance. A 4890 would be $189, and only nets me a 10% FPS increase for $30.
Since I have a $25 gift certificate to Best Buy, I can use it on this card:
