Windows7 install compatibility issue

First I hope I have posted this in the correct forum, if not please move to correct forum and accept my apology.
I have two computers that are running Win XP Home and one that is running Win Xp Media Center Edition. Will I have any problems upgrading the Win Xp Media Center Edition?
Currently I'm trying to upgrade the system with Win Xp Home. It has a Gigabyte AMD AM2 Socket (GA-M57 SLI-S4) motherboard, AMD Athlon 64 X2 Dual Core 6000+, 4 GB of ram and a Creative SB Audigy 2 ZS soundcard.
I ran the windows 7 upgrade adviser on the computer and then someone suggest I also run the vista upgrade adviser as well. On both it is telling me that there is a problem with "Windows Aero Support". I've seen lots of posts stating it will run on their video card but I have not seen anything on mine and need to know if I can upgrade to Win 7 Home Premium without a problem. My video card is a NVidia Geforce 7900 GTX. Does anyone know if that card will work with Win 7?
Then also it is telling me that my D-Link DWA-130 Wireless USB adapter is a problem. I went to their website and they have Vista drivers but not Win 7. Someone suggested not downloading the D-Link drivers but downloading the vista drivers and that it would work. I have little knowledge regarding Win 7 and therefore didn't know if this was good advice or bad advice on downloading the vista drivers. Is anyone here using this wireless adapter successfully with Win 7?
Last it mentions that it is not compatible with the Creative Game Port. I don't know if this is something that is downloaded with my Gigaabyte motherboard recovery disc. I don't think it was something I installed but not sure. AS far as I know it is not something I'm using so it doesn't matter if it isn't compatible (at least I think it's not). I didn't know if anyone knew about this.
I'm hoping anyone that has experience with any of this hardware will let me know if it is compatible with Win 7 before I upgrade it only to find it is compatible to upgrade.
Thanks for your time.

The Windows Aero support relates to the ability of your graphics card It could be (tongue in cheek) a pessismistic report from the upgrade advisor. I can see that there are Windows 7 drivers available. fwiw. I have a 7600 on one of my computers and it runs Aero 100%.

The D-Link will be a proble. I read this in an early review

"Pros: IT WORKS FINE WITH XP AND VISTA
Cons: COULD INSTALL USING VISTA CD BUT WOULD NOT CONNECT TO NETWORK.
LOOKED HIGH AND LOW FOR A W 7 DRIVER BUT COULD NOT FIND ANY.
Summary: OK TO USE WITH XP AND VISTA BUT ON W 7 UNTIL THEY PROVIDE DRIVERS. "
But they are not so expensive. A new one?

The Creative sound cards have given quite a few problems as you will see if you google. A quick browse seemed to say that there is no succesful Windows 7 driver.

The CPU (64Bit) also has a few problems, but the 32 bit edition runs fine.
All together, I doubt you will get much satisfaction moving on to Windows 7. You could try a seperate partition and install Windows 7 as a dual boot to test it, however.

Thanks for your response. Yes, I thought I might have to buy a new wireless adapter and they don't cost very much so I'm not too worried about that.
I know Creative is quirky anyway. I've had problems with it even in XP. The hardware and what it is suppose to do is great but the software stinks. Creative really blew their software and upgrades. Way too buggy.
I know this is off subject but any suggestion on a brand of sound card that is better?
So If I buy a new wireless adapter and soundcard, it should be fine? Correct? You mentioned you didn't think I would be satisfied with moving to Win 7. Why do you think that? Just curious as Win 7 beats XP and Vista hands down.
Thanks so much for your input.
