Please children, let's keep this related to the topic and not your problems.
As far as your CPU, it might be worth your while to look into the new Dual Core's that are coming out and a MOBO to compliment that. 80 dollars for a motherboard seems rather cheap it might be missing out on some key features. Also, audigy 2 is older hardware at this point, what about audigy 4 or the newest XiFi audio. But I myself still use my 5.1 included onboard sound and with the Logitech they are coupled with I have no complaints, so maybe spend the money elsewhere. 7800 GT or GTX are the way to go as far as fastest performance. All of these will have S-Video out to get your signal to a television for viewing pleasure (yay anime ^_^) Case sounds fine thats really up to you, 500 Watts though is very necessary as these new graphics cards use up a lot of wattage. Also, if you go with AMD it's usually a good idea to buy a third party cooling solution, check out www.coolerguys.com
to get a few ideas. 2 gigs of ram might be overkill for your uses but I guess it can't hurt :P. Hope this helps.
