Default what are the cheapest model gpu's that can be crossfired?

building my first build, 720p gamer rig and i'm intrigued by this dual gpu crossfire setup. Read you can save money and make 2 lower budget gpu's perform like a high end one. My goal is to make is a great 720p gamer 1360 x 768 and i figure that most higher end gpu's specialize in high resolution's that i won't need for a long while. Are there any 50-70$ graphic's card's that can crossfired for some decent 720p gaming? cheaper even if posssible. whats cheap that can be crossfired?

Crossfiring two low-end cards is not a cost-effective way of getting better performance. The real purpose of Crossfire is to combine higher-end cards to reach levels of performance that can't be attained by a single card. You'd be best off sticking with a single GPU, such as a 4870 or 4890 if you can stretch your budget to accommodate one.

No point at all coz the resolution is too low. Your resolution as to be 1080 or over inorder to reap the benefits of SLI/Crossfire. Get a decent midrange card ie 4870 like what BT said.

Oh, and crossfire doesn't always equal better performance when compared to one card. Crossfire/Sli sometimes doesn't work in some games and you end up getting only one card performance. Stick with a single GPU like a 4850 or a 4870.

Well if you where looking for two $70 cards, and if now you are going with one a 4850, or 4870 is for you. Or if you want the best bang-for-your-buck card, grab a 4890

found 50 dollar cards that can be crossfired last night, think they were 4550 or 4650

you guys sure it has no effect at 720p res? I figured 2 crappier gpu would be prime for 720p because they were designed for those kind of graphics while the 200+$ gpu's specialize in 25XX by 16XX extremly resolution's

think of how cool i'll look when i tell people that don't know much about pc's that i have a dual graphic's card setup

BIG PIMP'IN

Like I said already, there's no point in crossfiring two low-end cards, since you'll get better performance out of a single better card for the same price, and you won't have to deal with possible scaling issues (like Varroa said, in some games Crossfire doesn't work, so it'll perform just like a single card and not two).
