*note I somehow lost the papers that I got from the various stores today, but this is the gist of what that system included to the best of my memory.*
AMD Phenom X4 9750
Gigabyte MOBO w/Crossfire capability, DDR2 (4 slots) onboard sound and all the standard stuff
ATX Case
ATI Radeon 4850 512mb
2 GB DDR2 800 (Kingston I think)
Maxtor 500gb Hard 3mb 16mb SATAII 7200rpm
500w Antec Power Supply
20" Benq LCD Monitor 1680x1050 5ms & 2.1 speakers built in
LG DVD rw drive
2 yr warranty
Total Price w/ assembly and tax: $1178.00 (at current exchange rate)
Now I know I can get the parts cheaper in the USA, but I am sadly not there and with the AWFUL cost of international shipping I can't come out that well. Not to mention the fact that such types of items usually get stolen here. Also a 2 yr warranty is better than none if I do it myself (at least it is imo).
My questions, are as follows - other than the 2gb ram, which I can upgrade later, is there anything that you would change on this system? Also I would like to drop the price down to $1000 if I can, what would you suggest downgrading on first?
I will be running XP Media Center 2005 on this system. I need to be able to do some photo editing and occasional video editing for my job, and I like to play games in my spare time. Oblivion, Assassin's Creed, Farcry (FarCry 2 also when it's out), are the most graphics intense games that I play. I like to be able to play on high to very high settings with max resolution in all my games of course. XD I'm confident that this system can easily handle all of those games listed, but I also want something that I don't have to upgrade for a few years either.

Thanks for any and all feedback.
