Welcome to the OCN, it's great to have you aboard. thumb.gif

Thanks for all the help so far smile.gif

Here is the update:

I write from the new PC now biggrin.gif I'm still using my old video card, Radeon HD 5750 though but still planning to buy the Asus GTX660 2GB DirectCu II OC. Currently my rig is:

- i2600k at stock, because there is 0 fps upgrade if I OC to 4.8Ghz, because my GPU is now the bottleneck.
- 8GB Vengence RAM 1600 9/9/9/24 2T (should I change to 1T command rate btw?)
- the awesome cooler master HAF XB box case - it's beyond amazing! The front fans are loud as a jet though frown.gif
- Win7 64bit
- Radeon HD 5750 OC at 870/1430 which is the max the AMD drivers allow. The OC gives excellent results and boosts fps from 25 to 30 in AC3 in max settings (only AA is 1 tick down as it lowers fps by 10 with little gain in quality). Here's the result at ~30 fps in Boston:



GTA4 and SC2 run smooth on max settings, Crysis2 DX11 HDTex runs at playable settings on very high-extreme, but not on ultra. My goal would almost have been achieved even without the new card, however then I started modding Skyrim.. and the fps dropped like a rock xD My current goal is to run a photorealistic modded Skyrim enviroment in max possible settings at ~30 fps. A new card is a must. Here's an example:

Vanila Skyrim + HD tex from Bethesda - smooth fps all around


With currently applied mods - 17-18 FPS in this scene frown.gif Not even max settings.. no SSAO etc. It drops to under 10 on max.


When I OC the CPU to 4.8Ghz, I gain 0 fps here. Do you think 660GTX 2TB will let me play Skyrim with even more quality mods in at least 30 fps, or do I need to look for something even stronger?

And final question. I want to buy a UPS because the power is often cut here due to a lot building works going on in the city. I only need to hold the power for a couple of mins, 15 max, but I have no idea how strong it should be, to hold this rig with the 520W corsair PSU, and my LCD.. any advice? smile.gif Thanks.

Your CPU will NOT hold a 680 back, not even at 4GHz smile.gif Not less 4.8GHz

Check out this card, massive bang-for-buck for future games as well smile.gif

You're right the Radeon 7870 OC actually nearly matches a 660 Ti + it's 256bit.. also my previous GeForce 8800GT burned out, was replaced by my current Radeon 5750, which has not failed me. Another reason to go AMD again.. smile.gif

Whichever UPS you buy has to be able to provide enough power to keep your rig running at the time of the power outage. It doesn't matter how 'big' your PSU is, all that matters is how much power your system is pulling from the PSU. With one GTX 660 and a 2600K at stock, the most power your computer could ever possibly pull from the PSU is about 292W. If you overclock the 2600K to 5 GHz, then the most your computer could ever pull from the PSU is about 342W. While gaming with the 2600K at stock, the most your computer would ever pull is about 250-275W. With the 2600K overclocked to 5 GHz, your gaming power draw could get as high as about 300-325W.

 

Therefore, the largest amount of power the UPS would ever need to be able to provide to your computer in the event of a power outage is about 300-350W.

 

Now, adding in everything else such as your monitor, I would say that the figure goes up to 350-400W - maybe ~450W.

It's a computer!

If the fans are too loud i would highly recommend swapping them to corsair af120 quiet editions or gentle typhoons thumb.gif

Also i would rather go for the suggested radeon 7870 gpu. Memory bus is bigger and it performs better over the 660. smile.gif

Dont worry about the cpu bottleneck. It's overrated issue, everone are constantly thinking cpu bottlenecks in cases like new i5 + 680, something like old phenom ii would bottleneck 680 rolleyes.gif

Thanks! So does this mean I should look for a 450VA UPS, or does W and VA mean different things? I read some article that suggested a 1000VA PSU at least for a gaming rig, so I'm uncertain.. it's a huge difference.

450VA was close. Check this out:

zerospinPSUcalc2.png

 

 

Source: http://extreme.outervision.com/secure/psucalculatorpro.jsp (it's not free, but it's only $9.99 and then you own it)

 

Note: I told the calculator to have the 3570k at 4.7 GHz using 1.35V here.

Note #2: 23.8A on the +12V is only 285.6W.

 

This calculation was also done with 0% capacitor aging. If I do 10%, then I get this:

 

zerospinPSUcalc3.png

 

(25.9A on the +12V is only 310.8W)

 

 

If I do 15% capacitor aging, then I get this:

 

zerospinPSUcalc4.png

 

(26.9A on the +12V is only 322.8W)

Thanks for this, it's very informative. So in other words, I should get a 700VA to be safe, right?

Or 650VA like this one maybe? http://www.overclockers.co.uk/showproduct.php?prodid=UP-013-CY
Actually this one is getting good reviews and its 700 : http://www.overclockers.co.uk/showproduct.php?prodid=UP-017-AP

I don't know what UPS units can be recommended and which ones shouldn't be, but I do trust the calculations from this calculator.
