I'm in the market for a new PC. I currently have a 1.7ghz and was wondering if I should get a 3.0ghz dual core or a 3.0ghz HT machine.
I believe that MSP7 currently supports HT but most likely does not take advantage of dual core (I do not run background tasks at the same time I edit or render). If MSP8 will support dual core then it would seem that that would be the right direction.
Also raid 0 seems the best approach for the disks. Should the raid drive be partitioned to separate video work from the rest of the system?
Ideas and suggestions are welcome.
Thanks,
Steve
Dual core vs HT at same speed

HT makes it appear as though your system has two processors, but it is really just one processor with an instruction scheduler than can take certain non-conflicting operations and execute them concurrently. This means it can't get close to performing at 2x the computational throughput with HT enabled as the same system does with HT disabled.
The dual-core processors are a different story. They have two complete processor cores on one die, with separate caches for each core. This does allow them to execute anything concurrently (though there are restrictions on memory access beyond the L1 and L2 cache through the memory controller). A dual-core processor can achieve roughly 2x performance with appropriately written software.
Both HT and dual-core processors require that the software running on it create at least two threads -- if there is only one thread, only one processor (physical or logical) can execute it, and the other processor is idle.
Ulead has supported both HT and SMP (Symetrical Multiprocessing) for quite a while, and MSP and other Ulead products will take advantage of this during certain operations such as MPEG encoding. But a dual-core processor will outclass a HT-enabled processor of the same clockspeed / FSB / memory speed simply because it has two independent "engines" instead of just one.

From what I've read, DC behaves on motherboards designed for them exactly like a dualie. If that is the case, MSP7 already supports them (may need XP Pro).
From my experience, HT stands for HYPErthreading. At the most, it gives a 5-10% improvement in rendering speed in MSP7. Judging from Mark Dileo's benchmark test results, dualies are better than HT but still don't halve the rendering speed. However, I believe the problem is that rendering does not optimise CPU usage, under any conditions.
I haven't yet done any rendering speed tests in MSP8 so cannot say whether it will offer any improvement in this respect (wouldn't be able to tell you anyway - NDA!
