Im in the middle of putting together first build and dont know if it would be better to get two Sapphire 4670s - http://www.newegg.com/Product/Product.aspx?Item=N82E16814102820

or.... one Sapphire 4870 - http://www.newegg.com/Product/Product.aspx?Item=N82E16814102849

Two 4670s will be cheaper than one 4870, and i would think a lot more powerful... any thoughts appreciated

this is what theyll be working with.... i think it all works together, i hope

get a 5770, it may be a bit more, but then you get dx11 and newer gen cards that use less power while giving you more performance (about the same as a 4870)

never buy 2 low end cards to try to get mid range/high end speeds, it uses more power, creates more heat, and crossfire/sli does not give 100% scaling per card
 
1 4870 is more powerful than two 4670s. It's also cheaper (depending on the model and 512mb vs 1GB), and uses less power than 2 cards, and you won't have any crossfire-software headaches. Crossfire scaling varies according to different games, and cross firing two 4670s (two budget gaming cards) won't net you very good results.

For example, in Crysis, two 4670s crossfires at best, only gives you the performance of a single 4850. And a 4870 is about 20-25% better than a 4850.
 
A 4870 would be more powerful. Two 4670s in CF are more of a match for a 4850, but not a 4870. Not only that but if you get one 4870 now, you can add another in CF latter on, assuming you choose to do so before they are all gone anyway :D. As for the PSUs, the OCZ is o.k, but I don't know much about the Mushkin PSU. Make sure to research PSU tiers before choosing a PSU though.

right on... i knew there would be something to it. ill check out the prices of the 4850 but ill probably end up with the 4870. i could get one for a good price, but id rather get a more supported brand.. and what ive read so far seems like sapphire. and maybe xfx. but i like the sapphire's design... looks to be cooler(colder). cooler too i guess..haha.

and ive done endless research on psu's..... member of 6 forums. youve probably seen me. i like the ocz, but might go with the corsair. its tough(and about 40 dollars, for the same power.... it seems)

This is all so much work, every spare second iv had for about a month has been devoted towards this.... just want it to be perfect... i dont usually spend any money... at all. pretty simple guy.

If you can find one, I'd go for a Sapphire Vapor-X model. The cooler that they have may be small, but its vapor chamber is a real champ at taking away heat. Mine idles around 45C and loads around 68C in Furmark, and that's overclocked to 800/1100 or so, I can't remember what the RAM is at.
