New PC - Xeon or Opteron?
Pentium100:
OK, I now have all the parts, will build the PC during the long weekend (11-01 is a day off here).
CPU: 2x AMD Opteron 4238 (6 cores 3.3GHz, turbo up to 3x3.7GHz)
MB: Asus KCMA-D8 (got a crappy sound card with it, will most likely use it until I buy the proper one).
RAM: 32GB PC10600 Registered ECC (got them relatively cheap from work, planned to initially get only 16GB)
VGA: AMD Radeon 6870 (will pull it from my current main PC).
HDD: Seagate 1TB (borrowed a semi working one from work until I buy the 15kRPM one, SSDs are too expensive and with 32GB RAM may not actually be that much faster).
PSU: Corsair HX750 (Nippon Chemi-Con caps FTW, while I can repair broken PC power supplies, I do not want any downtime on my main PC and PSUs with active PFS have a nasty failure mode).
CPU cooler: CM Hyper TX3 EVO (one of the few that would fit and were available for immediate order, they should be OK at least for winter, later I may replace them with old Zalmans (Socket C32 is compatible with Socket 940 coolers))
Case fan: 2x Sunon EE80251B1-000U-G99 - 69.7m^3/h (no, silence is not my main concern)
Case: Chieftec (IIRC) 4U rackmount case (will move an old PC to another rackmount case to free this case for the new PC).
Honemi:
SSD will almost assuredly be faster even with ridiculous amounts of RAM. Noticeably so. But if you can't afford, you can't afford it.
Saras:
Well, a RAM cache is faster than an HDD or an SSD. So it depends on how he intends to use the share amount of RAM he has.
Honemi:
I doubt anyone will be running their OS off a RAMDisk, though. (Ignoring those Puppy Linux users).
That probably matters a lot less in Pentium's case since he's planning to turn this machine into a server anyway.

It won't be a server for a while though.
As for SSD - the main advantage of SSD speed is faster boot (not a problem as I will keep that PC on all the time), and that programs start faster (again, I will probably keep my most used ones launched all the time - I kinda do that now with 3GB RAM). Sore, games would load faster, but an SSD would have negligible effect on FPS. Also, if other programs don't use up all the RAM, Windows will cache most accessed files to the rest of it (probably resulting in a slow PC just after boot and a faster PC a while later). Also, programs that access a lot of data (but not too much) would work faster, but I rarely use those (like video encoding etc).
I think a 15kRPM HDD is a good compromise between an SSD and a 7.2kRPM HDD.
