you really think a F3 would be faster than those 2 in raid?! lmao. plus its not like those things are even reliable.
yea the 850 is a bit much but it's not that expensive and it wont be pushed hard so it will last longer... duh. plus it leaves more headroom if he plans to buy a new graphics card, or 2, in the future. plus you have to incorporate the extra power required to overclock cpu + gpus.
by the time the op will need to upgrade seeing that the 580 is such a powerful card, there will be no point in getting another 580. there will be 28nm cards which will make way more sense to get. 2 560 ti's perform better than a 580 and cost less. seems like a no brainer to me.
and there are no problems
... a problem implies that it wouldnt work.
650 watts would be a problem
. according to this review,
A second card requires you to add another ~175 Watts. You need a 700+ Watt power supply unit if you use it in a high-end system (800+ to a KiloWatt is recommended if you plan on any overclocking).
sounds like you're not as knowledgeable as you thought.Edited by revamper - 7/23/11 at 5:11pm
