I originally chose the 5770 for it's performance in addition to its power consumption. To date, I've not had a single problem with this setup and the most I've "ever" seen it draw is about 190W at the wall (using a Kill-a-watt). I was wondering if there might be a decent upgrade path from this card to a newer model with better performance. The only other two peripherals in the case are a slim-line DVD burner and a SSD as the only hard drive.
If anyone can make suggestions, I'd greatly appreciate it! Thanks!
