Not sure how much you want to spend (range not exact numbers) but I can duplicate those graphics with an x800xt (I have a PE, but have seen/read posts of people using x800xt Pro)
Seen the x800's going for about 190 up to 540 (USD) depends on your range...
This ATi card AGP so if you upgrade to PCI-e better rethink but if AGP using an x800 card with Omega drivers been real good in SH3...
g/l and good hunting!
