GTX570 for a Q6600?

[alejandro1254]

Hi, I'm just new to this forum, I'm from Mexico and just started with overclocking...
I have a Question, right now this is my system:

EVGA 750i FTW
Q6600 G0 2.4GHz OC @ 3.6GHz/450MHz FSB
Ram PC5400 OC @ 400MHZ 5-5-5-12
Nvidia GTS450 x 2 SLi
Cooler master Silent Pro 700W
Gateway 24" LCD 1920 x 1200

And now i want to Change my GPU's, for Two GTX570 and a new PSU of 1500W

The Question is, do you think my cpu or something else will bottlneck the 570's?

Thank you

i think your 2x450's are a good match for your Q6600. I think you'd see a bottleneck for gtx 570's in sli

One GTX 570 is a good match for your CPU at 3.6Ghz, but two is too much GPU for that CPU, but even so a Q6600 @ 3.6 should be enough to provide your cards with a playable frame-rate on just about anything. Unless you want to use 3 monitors I say go with two GTX 560 Tis instead and save a little money to upgrade the rest of your system when Ivy Bridge and Bulldozer are out, or whenever you feel your CPU just ain't cutting it anymore.

2-GTX570 would need a modern quad core (i5/i7) at 4ghz to keep up.

Besides, at 1920x1200, 2-GTX570 would be a complete waste. Maybe try 1- GTX570 and then you won't need to replace the psu.

1500w psu? LOL

 

[alejandro1254]

I used extreme PSU calculator and for my OC and the two 570's I'll need a 1085w PSU, so... I think a 1500W could be enough for a long time...
Ok, so two 570 it's too much for my Q6600... I will go for 1 570 and then soon I hope, change my CPU/MoBo/Ram and then think about a sencond 570, thank you so much.

There is no way your system would draw 1085 with 2 GTX570. You must have made a mistake.

2-GTX570 draw only 410w by themselves, how could the rest of your system draw 675w???

A quality 800w psu would be more than enough for 2 GTX570 and the rest of your system. If your doing heavy overclocking (gpu's) then I would recommend a 850-900w.

Well, I don't know... i went to http://extreme.outervision.com/psucalculator.jsp, and use this settings:
1 CPU
High enf Mo B
Q6600 G0 with OC (3600MHz/1.55V = 219w)
2 Sticks DDR2 SDRAM
GTX570 SLI
Regular SATA x 3
1 DVD/DVDRW Drive
8 usb
80mm regular fan x2
120mm regular fan x 4
120mm led fan x 1
swiftech MCP655 x2
20% capacitor aging
and a 100% CPU utilization and system load for worst case scenario...
Minimum PSU Wattage : 1055w


and that's why I think I would need a 1500w PSU for no future worries...

1500W PSU definitely still seems like overkill, even for future-proofing the system...
Also, 2 x GTX 570 would be a waste with a CPU like that. At 3.6 GHz I suppose 1 would do fine, but don't bother to SLI it. By the way, 1.55v is a VERY high voltage to be running the Q6600 at. You should try lowering it if you wanna preserve the CPU

I just have to back up what other people have said. 1500 is absolute overkill. Im running 1 570 on a 600w and no problems. With just a bit more I could do SLI. Save some money there and upgrade you mobo and cpu.

 

[desolator4u]

I had my Q6600 running near that same voltage until I had to replace my mobo with a cheaper one. I had water cooling system from micro center and my Q6600 is still running fine.

Wow, that's awesome man. From all the research i've done, it wouldn't be good to have it over 1.5v, but since you got water cooling, I suppose that allows you to go higher.

I have a Corsair H50 push/pull conf. and with 1.55V I have 40~43 on idle and 68~70 on load, so I don´t think it's too bad... and soon I'll upgrade my cpu/mobo.

 

[megamanx00]

I know people are saying the 1500W is overkill, but if you really want the 570s then I think it's a good idea. After all, if the setup is going to draw 1055W then that would be using 70% of the 1500W units capacity. Of course, that's really only worst case so a 1200W might be a bit more reasonable (1055 would be about 88% of it's capacity). The less you stress your PSU, the cooler it should run and the longer it's life should be.

I still say that two 560Tis would make more sense because your CPU would limit that setup anyway thus giving you the same performance in your rig if you had two more expensive 570s. It would also allow you to use a cheaper PSU ^_^. It's up to you.
