I'm not sure I'd say this card is underpowered. It wouldn't surprise me if this, like many X60 range cards, are meant to be compatible with the IGPs of APUs. If the next gen APUs are based on the 460 and can be crossfired, that's actually some pretty significant performance. Personally, I'm not sure if recommending the 4GB models, gaming or otherwise, is the right approach. I haven't seen benchmarks of 2GB models but it wouldn't surprise me if that performs roughly the same. This GPU clearly wasn't intended for 1080p gaming, so if you're at 720p or lower I think a 2GB model is plenty sufficient.
