Which should I get?? PSU question

[glenquagmire]

So I see some good deals on Cooler Master PSU (components are made by Sea Sonic) for 700v (full mod GOLD) and 1000v (full mod GOLD).

I plan on overclock:
-AMD FX 8350
-Gigabyte FXA990-UD3
-G Skill 2x4gb 1866 CL8
-Cooler Master Storm Scout II case
-7950 or 7970 GPU
-WinTV 2250 tv tuner
-Asus DVD Drive
-Will get Samsung SSD
-2 or 3 TB HDD

Which is perfect for me with how much room left? I may add another SSD later and Crossfire later.

700v $89
1000v $129

If you are going to Crossfire later the 1000watt although 750-850watts would be enough.

Yeh. For the cost of 800 the 1000v is cheaper. So if I crossfire, the 700 won't do? How about if I didn't crossfire?

It would be marginal but most likely do it with crossfire. Plenty for a single card.

Total system power with HD7970 CF peaks at 648watts http://www.anandtech.com/show/5805/nvidia-geforce-gtx-690-review-ultra-expensive-ultra-rare-ultra-fast/16

for $129, only $40 more, would you find value in buying ithe 1000 and not need it or stick with the 700w? would there be any better performance?

 

[rolli59]

PSU's do not affect performance. I would go with the 700 unless I was sure I was going to Crossfire.

what would crossfire or sli really do for me? what if i didnt game and only used it for media center, would crossfire or sli make it better vs one card?

No need for CF outside the gaming world and with a single HD7970 you will be fine with all current games on a single 1080P monitor

is that really where sli or crossfire matter, is on multi screen? I plan on using my one 60" monitor.

Well it is resolution not actual size. We could say that CF or SLI are needed on multi monitor setups on extended resolution where they have to process more pixels.
