MageB420666

I'm in need of a new computer because my laptop has finally crapped out. I'm going with a desktop this time because I really have no need for a laptop and I am on a budget. So far I've surfed newegg.com and come up with everything I need to build my own computer(I hope), and I've gone to dell and created a comp there for roughly the same price.

So basically, am I being a complete idiot with what I've come up with as a build-your-own? Am I going to get any better performance graphics wise from building it my self, or am I better off going with dell and saving myself some time and effort.
All I really need the computer to do is surf the web, play Guild Wars and various other games, and play movies. And I'm not a huge gamer either, I was playing GW on my laptop with a 32mb Radeon 7500(which is probably why its crapped out)

The Build it:
Case: Apex PC-115
Motherboard: Gigabyte GA-K8N Pro SLI 939 socket
Processor: AMD Athlon 64 3800+ Venice
Memory: Corsair XMS 512 (x2 for 1GB)
Hard drive: Seagate Barracuda 80 GB
Video Card: ATI Radeon X1300 pro 256 mb
Sound Card: Creative Sound Blaster SB0570
Power Supply: Antec Smartpower 2.0 Sp-500
Monitor: Samsung 940b
Misc: Keyboard: Rosewill RKM810SLV
Disc Drive: Sony DDU1615



The Dell:
2.8 GHz Processor (Pentium D)
Windows XP Media Center
Nvidia Gforce 7300LE Turbo Cache 256 Mb
1GB DDR2 SDRAM
250 GB Harddrive @ 7200 rpm
16x DVD Burner
19” Ultrasharp Monitor 1907FP Flat Panel

Thanks for any advise.
