bit-tech published a review of Creative's X-Fi XtremeGamer soundcard

For around £62 (inc. VAT), (or £56 if you are a regular contributor in our community and qualify for free delivery with Scan) the Creative XtremeGamer is a serious bargain. You might be a bit wary of investing in a PCI card, but the slots should still be around in motherboards for a few years yet, and it's a small investment compared to shelling out £150-plus for the top models. It's Vista support is really very good, although we'd still like Creative to include a task bar icon like they do in Windows XP.

Okay, you don't get the 64MB of X-RAM or I/O connector for expansion, but you still get a very capable card for entertainment, gaming and audio creation. Some people would argue that on-board sound does the job just fine, especially since many now offer the same extra Dolby and DTS that discrete cards use, but the sound quality of the XtremeGamer is just head and shoulders over anything on-board.
