Looking at these figures, the entire system with the 4870X2 under load draws 444W from the wall socket. So if the PSU is 80% efficient, the entire system is really only drawing 355.2W. From this, you can conclude that a solid 500W PSU might do.
However, you might want to check the 12v rails to make sure you won't be overloading them.
He's not Overclocking, so he should be *fine*, but you would need a better one if you were, and you will be bottlenecked unless you get that proc. to at least 3.0Ghz, so why don't you just pony up the money to get a new one ?
E6600 OC to 3,1 Ghz
But I think that G260 is too weak for the future ... playing at 1920x1200... or?
While it's your choice and decision to buy what you want, let me tell you this: You buy today's video card to play today's video games. You should not buy into the scheme of "future-proofing", since by the time the future comes, there will be video cards that surpasses the 4870X2 for $200. If you feel that the 4870X2 is worthy, by all means, get it. Playing at a res of 1920x1200 is no easy feat, but that depends on the game.
Enermax is normally a high quality PSU. If it does what it's rated for, I'm sure it'll be fine. There might be some rail balancing to do if there's multiple 12V rails to make sure none of them gets overloaded though.
I did this all yesterday on the psu calculator, and it showed with his current system and cpu oceed at 3.1, 263 watts. Maybe I missed something in his setup, but the oc on his cpu was 84 watts. Im thinking with a 260 hed be ok
4870. Theres supposedly an upgraded 260 coming out in a month, and itll be better. Right now? The 4870 is a tad better overall. But, when it shines, it really shines. In some games, itll outperform a 280. That simply cant be said for a 260. Plus, the extra 20 pounds will let you go out n buy some beer
Im not sure this is correct. There may be a card coming, but opening it up like theyve said could cause other problems, making it imbalanced. My expertese in this isnt that good, and I refer to Ape or someone more knowledgeable than I. But this may be just a 55nm G260, and theyve somehow skewed whats really going to happen. It sounds nice, but will it work? Anyone seen a purplish looking Ape running wild round here?
