Re: New desktop
This is quick off the top of my head:
Motherboard: Intel BOXDP67BGB3 LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard --- $180
CPU: Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 --- $320
RAM: CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) --- 50$
Video / Graphics Card: XFX Radeon HD 6870 2GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support --- $210
Sound: 7.1 Realtek - Onboard
Optical Drive: LG DVD+/-RW SATA Drive - any for like $20.
Power Supply Unit: CORSAIR TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified High Performance Power Supply --- $95
Case: Antec Three Hundred Illusion Black Steel ATX Mid Tower --- $60
You can find all of these on New egg - this is prices off there including VAT, and most have free delivery.. There was a few bonus / promo codes as well as rebates on there, which could knock a bit off the final bill. The above totals to about $930. I havent included a wireless adapter however.
If you shop around, use the same website for everything if possible, and look for codes / rebates you could easily knock $40 or so off the $930 above. (The case alone has $10 off at the moment)
Just for your information, a Phenom X 6 is the rough equivalent to the i7, although not quite as powerful. It however would give you a cheaper 'all round' build than an intel build. Sorry for lack of links - on the go now.
EDIT: Just realised you didnt mention A hard drive. Any is fine, If you want a fast / reputable brand, go for the Western Digital Black Drives - Although they are expensive. As for suggestions you could get a SSD (Solid State Drive) to increase speed - but this again hits your budget, and the rig itself should be fine without it
