Hello,

I was originally going to run crossfire with

SAPPHIRE 100245HDMI Radeon HD 4850 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail
http://www.newegg.com/Product/Prod [...] 6814102824

However it was suggested that one

XFX HD-577A-ZNFC Radeon HD 5770 (Juniper XT) 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail
http://www.newegg.com/Product/Prod [...] 6814150447

would be better. Any suggestions i do not wish to spend more than 200 on the card/cards.

Also the two boards im looking at say the fallowing the gigabyte says PCI Express 2.0 x16 (2) ;however, the Asus says PCI Express 2.0 x16 - 2 (one x16 or dual x8 link). Does this mean that on the gigabyte board crossfire could run at 16x while on the asus it can only run at 8x?

GIGABYTE GA-MA790GPT-UD3H AM3 AMD 790GX HDMI ATX AMD Motherboard - Retail

ASUS M4A79XTD EVO AM3 AMD 790X ATX AMD Motherboard - Retail
http://www.newegg.com/Product/Prod [...] 6813131402

thank you any help would be appreciated, and thank you for reading the post as well as your time. :bounce:

If you can wait, 5750 512mb would be launching at $109. You can use two of them in crossfire.

Well, two 4850's in crossfire will only be slightly better than the 5770. (Just a couple of frames)
My suggestions is to buy a 5750 now, then crossfire with a second one after the prices drop (Should be around the time that Nvidia releases their DX11 gen.)....or just get the 5770. I tend to overthink my purchases. :)

@the second question: Yes, that is exactly what it means.

The 5770 has performance equal-to or less-than the HD4870. 4850x2 > 4870 by far.

Not true at all. A better comparison for crossfired HD4850s would be an HD5850.

A 4870 is faster than a 5770.

check this deal, its 2 x 4870 1GB's and a 700w psu for $269.

http://www.newegg.com/Product/Comb [...] mbo.273279

and 15% Off Code TTOCT15 = $269

Zipzoom has an extremely great deal, AngeKnight. That's the best you can get.

It's also $70 more than they said they want to spend though.
Tell us what monitor and/or resolution you plan on using so we can give a proper recommendation.

He said his budget was $200 for the cards.....how do you know he doesnt need a psu too!

Or he could sell one of the 4870's for $150 on ebay and get a 4870 1GB and a 700w psu for $119.
