I cant find a good way to compare them.... but both have pretty bad benches.
5450 fares better in the 2 games I could find in common between reviews.
It still doesnt hit 1k in vantage.
EDIT: buy this one. http://www.newegg.com/Product/Produc...td.-_-14161303
It destroys both. Like more than double the power.
2100+ vantage... wont get better for $50.
