I didn't want widescreen at first, but all 22" were widescreen. Boy am I happy I got it. Love it.
For your soundcard, barely any games actually support that X-RAM. Just UT3 and a handful of some other titles. I wouldn't take that card for it's X-RAM.
I bought a X-fi XtremeMusic not all that long ago (didn't like the XtremeGamers halve PCB, although it actually is a bit more practical). It's a PCI card, not PCI-E. It has the same stuff like that fatality version, except it doesn't have X-RAM, which doesn't really make a difference these days. It used to, a few years ago, but not anymore.
Anyway, I hate my X-Fi. Spent 70 EUR on it ( 105 USD) and the damn thing is hopeless. It was a pain getting it working in the first place and when it does it will stop working every so often. I'll sudenly get a very high pitched sound from my speakers and I'll have to change 'mode'. Changing mode will make all applications using sound at that moment to stop (the sound). So if you're gaming, you have to restart. Many times I'll have to even reinstall the drivers after switching mode, because they'll just mess up. Don't have that problem with the new drivers though, now the card will just stop fully, or only work in 2.1, which sucks.
If you've got 64bit Vista, do not get it (yet). I know other vista users (32bit) with this card and it works for them, so my card might just be broke or I've got faulti PCI slots.. One thing is that I just can't get the card fully into the slot in the first place. Those pin like things still are a bit visible and the right side of it (the side facing front of your PC case). I'll attempt to get it working later in the day, again...
I should add that when it does work, you've got some very good sound. Music sounds better, games sound a bit more 'full' and surround is much more accurate. Also, it upscales your music from mono/stereo to surround, which IMO it very nice. That's the main thing I'm actually missing now.
The headset is great, I've heard. So that's a good buy I think.
The speakers... I went for a G51, which is a great set, but though I can't say anything bad about it and I love it, I could have gone a bit cheaper.
I've got a friend with the stereo version of the X530 and that one sounds quite good too (powerful bass BTW), and I was considering buying this one too. But after reading reviews and stuff, it seemed getting the X-540 would be a bit better buy. Just 10 EUR more (here. Don't know the US prices). But there isn't really a big difference. X-540 is a bit louder and has a bit better bass. But they fail in the looks department.. I like the style of the X-530.
So, boils down to this:
All looks good, but you might just want to go for the XtremeGamer or XtremeMusic instead, since that X-RAM is barely going to help at all.
And 22" is a very good choice for a monitor. Personally I could have gone for 24" too (thought it was a bit too big when I was in a shop). But these 24" displays are much more expensive too.. So probably wouldn't have done that. Also bare in mind the maximum reso for these 16:9 displays (22") is 1680 x 1050. You won't be able to get these full HD reso's. Doesn't really make a difference though.. Thing is, I'd think 22" is a little small for TV and console games (unless you stay at your desk). I wanted to make my monitor a TV too, but decided to get a 40" LCD TV instead and hang it up on some wall in my room (I'll be buying it Q1 2009). But that's only for watching TV at a distance. If you're going to stay at your desk doing that would just be insane, though I'd in that case still go for 24".
Really depends on how much money you're willing to pay. If you've got a limited budget and not planing to use your monitor you'd use an actualy TV, 22" will be enough. But I like the idea of watching TV from my bed before sleeping, so I'll need an actual TV for that.
I watch movies on my 22" and I've got one of these gaming monitors and that isn't actually the best thing to take for things like movies. So just mind that when you're buying your monitor.
But it looks all good though. Main concern would be that X-Fi.
