My friend wants to build a new computer with a budget of around 850-900 USD. He already has a DVD-RW drive and a 500GB HDD.
APPROXIMATE PURCHASE DATE: 2 - 3 weeks
SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Video editing, photoshop, gaming
PARTS NOT REQUIRED: DVD-RW and hard drive
PREFERRED WEBSITE(S) FOR PARTS: any legit website goes
PARTS PREFERENCES: He wants a i7-920 and a X58 mobo
SLI OR CROSSFIRE: No
ADDITIONAL COMMENTS: He is also looking for 6GB of ram. He also doesn't need a high end video card, just a mid level card like the GTS 250. I don't know much about ATI's new lineup, but if the value is good then that would be good also.
The i750 system will perform almost as well as the i920 system, and should save you about $160. Your other option would be to stick with the i920 system and get a cheap X58 motherboard, but these cheap motherboards have a bad reputation for being unreliable.
Another option would be the i860 processor, which will outperform the i920 system, and save you about $80.
