A quote from the article:
>> VisionTek HD 4770 Review
If about a $100 USD is your budget though, the VisionTek HD 4770 is a safe bet that just might surprise you. It is less expensive than many similar HD 4770's selling today, comes with a Limited Lifetime Warranty, and certainly has enough horsepower to keep your gaming sessions 'high' -- not running at medium, and not lacking AA.
