1) Running RAID0 improves sequential performance. It does very little for random performance. The vast majority of OS and application loads are random intensive.
a) RST caches whatever needs to be cached regardless of disk source.
b) Depends on your work patterns. If talking about random performance, there is no difference. If talking about sequential performance, the RAID0 generally performs better.
2) Not always. Newer 10K RPM are faster than current 7200 RPM. However, older 10K RPM are not. That being said the cost-benefit of the higher RPM is pretty low... 2-3 times the price per GB for 5-15% performance gain. The money probably would have been better spent on a larger SSD for most.
a) No. If the system is able to access what it needs from the SSD, the HDDs are not hit. Otherwise, the 10K RPM would perform better than a 7200RPM regardless of RST.
3) A dedicated SSD does provide better performance. RST is useful if everything that require random access does not fit on a SSD though or if end-user does not wish/know how to manage partitions. RST (my personal belief) will be standard in 2-3 years.
a) Depends on budget and technical saavy.... probably dedicated SSD for you.
The Corsair H100 is avaliable now.
The PSU wattage is more than you need unless you plan for tri-SLI.
Is the Xigmatek Elysium avaliable in the US yet?

Hi Alucard, just to share - seen some bench test done by users in forum.
RAID 0 + 311 SSD = lower sequential write peformance than RAID 0 - example from RAID 0 - 180+ MB/s, it went down to 160+MB/s with smart response technology turn ON
single drive + 311 SSD = higher sequential write performance than single drive - from 80+MB/s, it went up to 200+MB/s
my personal take is RAID 0 + 311 SSD as cache as this setup would boost your 4KB/512KB performance to 2 to 3 folds, bench test shows < 1MB/s with RAID 0 only, you enabled SSD caching, it went up to 17+MB/s. the downside is minor dip in the sequential area of around 20MB/s to 30MB/s.
Allright guys, so what i make up from your comments is, buy two 7.2K RPM drives in raid 0 OR buy a SSD just for OS/raid 0 and SSD SRT, the 10K RPM drive wouldn't give me any help.
Thanks for answering! was really helpfull
H100 isn't out here yet, but will come this month.
Xigmatec Elysium has been out here for a few weeks, but i live in Belgium ( Europe) not America.
The 1200W PSU is just ' to be on the safe side' since one of the main reasons i buy this new pc is to be able to overclock it ( old pc's were OEM and thus not able to overclock) if i use ANTEC's PSU calculator with the fact that i'm overclocking, it gives me a worst case scenario of 1300W even.
