Hi guys - thanks for the excellent advice, as I too am now at the sound card comparison stage.

Randar007 is right to be concerned about Windows 7 support - at least, where Creative is concerned.
Creative may officially 'support' Windows 7, but like myself and Randar007, many people (XFI-range users in particular) have experienced major problems when they upgrade from XP/Vista to 7.
It is not reassuring to see that despite these well established issues, the last official Creative Windows 7 XFI drivers were released back in May 2009, with one subsequent minor release that only fixes their 'auto update' software.
I can only speak for Creative and, like Randar, was hugely impressed by the performance and compatibility of my XFI XtremeGamer card with XP 32/64, but my experience over the last 48 hours has turned me off Creative for life.
I have more than little (perhaps less than alot) of technical knowledge when it comes to installing, building, tweaking etc, and I spent over 8 hours patently running through what I am now fairly confident are almost known fixes for my Windows 7 install problems via the helpful (user community) Creative forums.
A couple of searches in these forums will reveal a lot of irate users with a shockingly wide range of issues. Although many of the problems are fixable, the general consensus seems to be that their customer service is almost non existent. As a result, almost all of the fixes and driver packages are unofficial, designed by enthusiasts who have built up a whole community of followers as a result of Creative's pathetic support.
I'm certainly not knocking this card on performance
when it works, but it seems that there's an unusually high overall occurrence of Windows 7 setups that Creative XFI drivers simply do not like.
I'll be selling my fully functioning XtremeGamer card on eBay, but I'll feel morally obliged to warn any buyer to read up on their system's compatibility before attempting an install on Windows 7.
Based on the info in this thread, and the favourable compatibility/performance/support-themed reviews found elsewhere, I think I'll be giving the HT Omega Striker a go
Does anyone have any other suggested sound cards to throw into the mix?
