I want to buy a "Cooler master Cosmos" with PSU of 850W. The "RS-850-ESBA".
And the rest of my system will be.
GFX cards : 2x XFX Radeon HD 4890 1GB GDDR5 (crossfire) RAM : OCZ Platinum XTC DDR3 1333MHz 6GB KIT (3x Platinum Z3 XTC 2GB, CL7-7-7-20, 1.65 Volts, 240pin) Mainboard : Gigabyte GA-EX58-UD4, X58, Socket-1366 CPU : Intel Core™ i7 Quad Processor i7-920 HD's : WD VelociRaptor® 300GB SATA and 2x Western Digital Caviar® GreenPower™ 1TB
+ Fans and a dvd rom
I have read a lot of articles to see how much power all this uses on full load, and
i came to the conclusion that this power supply just barely would make it.
but i might be wrong, im not an expert in power consumption.
What do you guys think ?. Can the PSU handle this computer ?
And i that case is there more power to spare, in case i need more HD's and such?
Why would you want QuadSLI? It's buggy and low scalability.
By the time you want more performance R800(2xRV870) or G300 would be out, stomping any previous-gen. in SLi/Crossfire in dust. History repeats itself many times.
2x HD4890 uses slightly more power than a single GTX295 so no problem there.
And yes, sounds fair to wait for the 300 series. And i will actually.
The reason i'm so damn into this "must have super GFX power" is mainly because i'm
going from making machinima in BF2 to other games like OF2 or Crysis. And i need
the juice. but 1 single GTX-295 will do... saves me some money at least
With the mainstream being 1680x1050 and now 1920x1080 a single top-end GPU will be able to power all modern games (except the overkill CryTek engine) above 40FPS at minimum, even with 16xAF switched on. SLi or Crossfiring two top-end GPU is really meant for resolution 1920x1200 and above to take full advantage (at current generation of graphics). At 80FPS and above you won't notice the difference.
It's a sharp increasing curve if you graph resolution/$ when it comes to gaming.
