well the computer i am building i am getting solely from newegg and its costing me about 1100 american... i would say its a high-mid end machine (if thats how you say it)
evga 6800 GT
Athlon 64 3200+ Venice Core
Gigabyte GA-K8NF-9
Corsair 2x512 MB Ram
Antec 500W PSU
Western Digital Raptor 10,000 RPM 74 GB HDD
So you have enough room to even upgrade some stuff on there a little bit. Anything similar to that should be within your budget. Hope that helped you.
