i am buying a pc and i have decide all the parts i want except for the gpu. i need you guys to tell me which is better to be used in my system. The system specs that i have chosen are
amd phenom 2 x4 965 be 3.4ghz
4gb RAM DDR3 1333mhz
asus m4a785t-v evo
budget is roughly around $1000
the choices are 2 ati radeon hd5770 crossfirex/ one ati radeon 5850/ one ati radeon hd5870
i have read the reviews and the specs of each cards but i am still not unable to convince myself on which to buy.
for the suggestions i don't mind if you guys give me other cards for considerations ( i accept both ati and nvidia) because i am still on the process of making a decision. however please tell me the pros and cons of each of the cards that you suggested.
please help me in these matter.
Get a 5850 or 5870 over 2 5770s, so you can still upgrade in future and get a nice performance boost.
And with your build, get a 790fx chipset mobo, so you can do 16/16 cf/sli, i believe that mobo only does 16/4 cf/sli?
then it means that i need to get a higher psu to support the cards right?
and for the cpu i need to get a 965 with c3 stepping and for the motherboard a790gx or 790fx is better. while for the gpu it is better to get a single 5850 rather than 2 5770 and a 5870 as the price is cheaper than a 5870, performance is nearly similar though slightly lower than a 5870, and it does consumes less power than a 5870 right? just to make sure, does the 5870 have any superiority over the 5850 that make it much better ( does it really make difference in gaming and application compared with the 5850 )
Any 600w PSU should handle an HD5850. If you plan on crossfiring 2 HD5850s at some point then you probably want to consider a 700w PSU although the 600w may be able to handle it if it is a high quality brand with good amperage on the +12v rail.
Looking up the m4a785td-v it seems the crossfire is only x4 on the second slot so I would recommend a different board instead; http://www.newegg.com/Product/Product.aspx?Item=N82E168...
