8800GTX to 4870X2 - Do I need to upgrade anything else ?

[BeelzebubUK]

I game at 1920x1200 so I'm thinking about upgrading from my trustworthy 8800GTX

Space is tight inside my case (Silverstone LC20). I've already had to cut a section out of the drive cage to fit the 8800GTX but the 4870X2 is apparently the same length.

Just wondering if I'm going to severely bottleneck it with my current spec :

Motherboard : Asus P5W DH deluxe
CPU : Q6600
Memory 4GB OCZ (cant remember speed)
HD : 2x 150GB Raptor Raid0
PSU : Corsair HX620W

Depends on the CPU speed, 3Gig on the CPU will be fine for gaming, but will hold back benchmark results, under 3gig and you'd be holding back the GPU in games.

What's your PSU?

Not overclocking at the moment so just the stock 2.4Ghz. Haven't tried to overclock it but guess I could reasonably expect it to get to 2.8-3.0Ghz judging by other benchmarks

At 2.4Ghz it will be holding you back quite a bit, ideally you want to clock it to 3ghz+

What CPU cooler do you have? Your Q6600 @ 3Ghz + and a 4870X2 will be very nice.

Even with the bottleneck, it will still be quicker.

3Gig should be an easy overclock with zero risk, dial in the bus at 333, set the memory divider to match your RAM speed, no need to increase vcore in 99.99% of cases. Might need to increase NB voltage +0.1 if your using a lot of RAM or faster RAM.

Just make sure PCI/SATA and PCI-e buses are locked and not increased with the FSB.

Got a Scythe Mini Ninja with a 120mm fan on it. Can't put any bigger heatsink on it due to the case height. Cooling should be OK as its in a nice airy position with 120mm fans blowing in and out.

Thanks for that - i'll give it a test run tonight.
