Sapphire Radeon HD 5830 Xtreme for $155.
Used for a few days.
Never flashed the BIOS or did any voltage modifications.
Card never reached temperatures above 65 Celsius.
Card is very stable at speeds of 300Mhz Memory / 990 Mhz Clock.
It can pull 306 Mhps and has never crashed or restarted. Seems like it's a good one.
Will include everything that came with it (cables, packaging, original box, etc.)
Again, price is $155. I will also accept Bitcoins equal to $155 USD at the time of payment.
PM me or Email me at the email in my profile.
Edit : I am located in the Chicago area and I would also be willing to sell this locally for cash or bitcoins. Meet up in a public place kinda thing.
