RAM - Corsair Core i7 Dominator 6GB PC12800 DDR3 RAM - Tri Channel, 1600MHz, 6144MB (3 x 2048MB) -don't know if this is good... I've been told that I can support my CPU perfectly well with triple-channel RAM at only 1066MHz, 1333MHz is bonus and any faster than that is overkill - that I should concentrate on very tight timings at the slower (1333MHz) speed, with a note that I require only 1066MHz RAM in triple-channel to get the same memory bandwidth as 1600MHz RAM in dual-channel... not sure what that all means....
Case - Caught between 3: IN WIN Maelstrom (I don't know why, but I really like the case...it looks good for the price, full size and good ventilation), Cooler Master HAF 932 Full Tower Black Case (good ventilation) or the COOLER MASTER RC-692-KKN2 CM690 II Advanced Black Steel ATX Mid Tower Computer Case (its smaller and not sure about how it will handle two GPU's, but its nice)
CPU Cooling - I have no idea at all. I am totally stuck here. I thought about the CORSAIR Cooling Hydro Series CWCH50-1 120mm High Performance CPU Cooler but was worried about it leaking. I also looked at the Coolmaster v8, but that thing looks freakin' insane! And advice?
Any advice on a different setup, pricing, opinions, etc. please advise.
Thanks very much
1st Mobo:you can't decide and i understand so here is a little help, three new flagship LGA 1366 Motherboards rounded up for you here and i would go for the R3E for great efficiency but if it does not fit the budget i would go for the BigBang from MSI.
2nd GPU:the gpu HD 5850 is a great choice and there is no point on spending another 100$-150$ for the HD 5870 if you are going to Xfire the HD 5850.
AMD architecture favors tighter timings over faster speed for
performance increase. Intel, favors neither. That said, neither makes
a significant impact on performance to warrant a major price
CAs latency refers to how long it takes the RAM to do something after
it's given a command. Makes no difference to FPS in gaming, but like
an SSD, it improves system responsiveness.
Stock i7-930 is 133 block, 21 multiplier and 10x memory multiplier.
Though the latter is determined by MOBO not CPU. This fully saturated
1333mhz RAM. 133block speed x 10 memory multiplier= 1330.
To OC above this you'll need to either lower multiplier or get faster RAM.
In general, we recommend DDR3 1600 RAM if you plan on a OC.
Now, the reason why we recommend G Skill RAM is that memory can
perform better than rated speeds. Most companeis sell you RAM that'll
perform at specs, G SKill tends to give you better than you pay for.
So their RAM can run at higher speeds, lower voltages and/or lower
timings than specs. OCZ is the opposite, hence we don't recommend
High speeds requires looser timings to work. I'll avoid the
tech details as to why, but suffice to say this is a mechanically
imposed limitation. Now, because faster RAM must be of higher quality
to maintain the same latency as slower RAM, they're generally better
quality. As a result, the Trident DDR3 2000 kit that's rated at cas 9
at 2000, can hit CAS 6 at 1600 speeds. CAS 5 at 1333 speeds. This is
why people will buy extremely fast RAM. They're getting higher quality
RAM so they can run it at tighter timings for the speeds they want.
Now as to why 1600 7-8-7-24 kit is better than a 1333 7-7-7-21 kit, is
because, the 1600 kit can run 7-7-7-21 when under clocked to 1333
