I hvae said this in a another thread and i will say it again.
i am leaning more towards the 5870 card. why? because its alot cheaper, cooler and the 10-15fps gains you get on the 480 is not worth it imho especialy when the fps is near the 100's.
seriously, who cares if the 480gtx can do 120fps while the less expensive more cooler 5870 can get around 80fps on the exact same game and settings?
I tell you why the 480gtx will cost a lot for me.
first thing is the obvious starting price of £400+
2nd thing is the amount of heat and power in generates. i only have a 600w psu with about 4 hdd's an i7 quad core cpu, 1 dvd drive(going to buy another one) and about 6 120mm fans cooling my system.
For me to have a bit of peace of mind i would need to buy a new psu thats 1000w or above and a decent one of that range is over £100.
Summer is also coming along and things will only get hotter so possibly i would also need better case fans as im only using lian li stock ones or water cool the gpu which will cost another £100+
As you can see now, £100+400+100 i around 600 in total to get a 480gtx running fine without anyworrying if my psu is overloaded or the temps going above 90c in the summer.
With a 5870. i dont need a new psu and i dont need a new cooling system. i spend £300 on it and i could use the extra £200 to maybe buy more ram(only have 3gb) or maybe a 1080p monitor.
In a nutshell the 480gtx is too much for the performance gains. None economical and need to re-do my cooling and psu on my pc which adds to the cost of it.
ATI may not have the fastest card now, but for me, speed is not everything in games or else i would have bought two 4870x2 last gen but as stated above, im not interested in a gain of fps from 80-120fps. what im interested in is a gain from 30fps to maybe 50/60fps and none of the benhcmarks have produced results on that ie crysis and other demanding games that no one can play above 30fps in insane resolutions
