Hi,
 
I am going to open a Game Station for rent. Mostly I use my computers for LAN/Multiplayer gaming like Counter Strike, Warcraft DoTA, Ragnarok and the like. Anyone pls help me determine the specification of these 2 system. Which one is better for my business above, since my budget is pretty tight and considering I will just able to upgrade it for the next 3 years.
 
Any opinion will be much appreciated. Thx.
 
Spec #1:
Intel Pentium D 820 2.8 Ghz Dual Core (FSB 800, L2 Cache 2 Mb)
Mainboard Foxconn 6227MA-RS2H
DDR2 V-Gen 512 Mb PC4200
HDD Seagate 80 Gb SATA
VGA Eagle Nvidia GeForce 7100 GS 128 Mb PCI-e
 
Spec #2:
AMD Athlon 64 3500 (AM2)
Mainboard ECS NForce 4MA
DDR2 V-Gen 512 Mb PC4200
HDD Seagate 80 Gb SATA
VGA Digital Alliance Ati Radeon X300 SE Hyper Memory 256 Mb PCI-e

 
The AMD system is what I would choose "in this case" as your best system for what you want.  As for the graphics of that 2 I wouls ay the Intel one has the better graphics.  Maybe they can swap the video cards for you.
