Hello Raito, concerning your specification, I would look into purchasing one of the
P35 chipset based motherboards since they offer great overclocking potential and are all around brilliant boards. The only reason i would choose one of the Nvidia chipset based boards is, if you are looking at going SLI in the future.
Moving onto the memory, the Crucial Ballistix is great memory however may I open a few other options up for you. If you are looking to overclock your Q6600 to around the 3.4GHz mark then may i suggest the
OCZ 2GB (2 x 1GB) PC2-6400C4 Dual Channel Platinum Revision 2 XTC Series DDR2, which for the price, you cant beat it. Now even if you keep this particular memory running at its stated speed of 800MHZ, it will take your Q6600 all the way up to 3.6GHz. I am also pretty sure, this memory wont have any problems reaching the 900MHZ mark anyway.
Another memory kit that you may be interested in is the
OCZ 4GB (2 x 2GB) PC2-6400C5 Dual Channel Vista Gold Series DDR2, they come in the form of 2X 2GB which will allow for upgrading to 8GB in the future if need be. However that's not really the main reason for suggesting these, the main reason is the price, £82.24 inc VAT for this sort of memory is phenomenal in my opinion. Though please take into account that if you are looking to run your Q6600 above the 3.6GHz mark then do not get the above since these, very much like most of the other 2X 2GB memory kits out their, they are very limited in terms of overclocking potential.
May I also suggest, if you are looking into overclock the Q6600 then look at changing the Artic Cooling Freezer. Now their is nothing wrong with the Arctic Cooling Freezer 7 Pro CPU Cooler, for the price, it does a great job however, it could well hold your overclock back. Have a look at either the
Tuniq Tower or the
Noctua NH-U12F. I have heard a number of very good reviews for the above CPU Coolers.
One final thing that I have to mention is regarding the Power Supply. Their is nothing wrong with the OCZ StealthXStream, I have read a couple of good reviews on them but even having said that, i would still be very weary of it based on the price. A Power Supply is one of the most important components that is in your machine so in my opinion, you should never look at getting a cheapish power supply unit. The power supply I would recommend would be the
Corsair HX 620W ATX2.2 Modular SLI Compliant PSU, having heard a lot of excellent reviews on this particular power supply and having one myself, I can't praise it highly enough.
