My gtx 285 tri sli setup, how far should I overclock my CPU ?

I am gonna start ordering the parts by Monday. Till now I have the following config in mind.

------------------------------------------------------------------------------------------------------------------------------------

CPU : intel core i7 920

memory : CORSAIR XMS3 6GB (3 x 2G 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model TR3X6G1600C7 G

GPU : 3 X EVGA 01G-P3-1180-AR GeForce GTX 285 1GB 512-bit DDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Card

hard drive: Western Digital Caviar Black WD1001FALS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drives

dvd burner: Sony Optiarc DVD/CD Rewritable Drive Black SATA Model

Computer case: Antec Twelve Hundred Black Steel ATX Full Tower Computer Case

PSU : CORSAIR CMPSU-1000HX 1000W ATX12V 2.2 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS Certified Modular Active PFC

I wanna know how far can I overclock my CPU keeping the stock CPU heatsink ? will it be enough for playing games at that resolution ? or should I go ahead and order a new CPU cooler ? Personally I dont want to overclock too much.

If you can, do get a D0-stepping of the 920. I read it overclocks better than earlier steppings

Was just thinking to myself.. will it actually be beneficiall to have 3x GTX285's since ur pci-e buses are (x16/x16/x8)?

What about Having 2x GTX285's in SLI with the PhysX processing disabled and have a third card, maybe something like a factory overclocked GTX260 Black Edition solely dedicated to PhysX processing. It will free up your 2x GTX285's to concentrate purely on graphics and with the games that require a PhysX processor, the 260 should hav no problems at all.

If the 260 can handle the latest games on its own, am sure it would manage with the PhysX when neeeded.

It will save you a bit of money since the 260 black is only £148 http://www.scan.co.uk/Products/896MB...V-plus-FarCry2

For all the performance a 3rd in SLI is going to give you, i doubt it would be worth it. Maybe it will, just my opinoin... Thanks for reading

Total waste of cash dedicating a medium to high end card to Physx processing.

Benchmark-wize u will see some lovely figures.

In real life - which is what counts - there isn't a great processing demand.

That's kind of the point i'm trying to make with the 3x 285's though. Bit of a waste of cash too. Personaly if i had the money, i'd just get the 2x 285's and not bother with a 3rd but from the post i think he wants to go over the top

just remember mate that Gen 2.0 x8 is as fast a Gen 1 x16 the third card will still make a great impact in gaming, also physx only needs a 8800gt at max

I'd say a 8600 is overkill - BUT the thing is they're relatively cheap.

I wonder how a £30/40 8400/8500/9400/9500 would do ? Bet they'd do fine.
