I'll need a new PC in the near future and from what I've read so far, I'm torn between the 4770 and 4770k (because of TSX and price difference). ta Danny ID: 75486 · Rating: 0 · rate: / Reply Quote

Doesn't BOINC just use a series of single threaded applications, assigning one instance to each thread? ID: 75487 · Rating: 0 · rate: / Reply Quote

Rosetta@home work units run in a single thread and this allows BOINC Manager to run several work units at the same time of preference settings allow it. [edit] I take it back, I believe the graphic and watchdog are threads... but they aren't doing the actual task crunching. Rosetta Moderator: Mod.Sense ID: 75489 · Rating: 0 · rate: / Reply Quote

Looks like the 4770k is the one to go for then! ID: 75490 · Rating: 0 · rate: / Reply Quote

I'd get the K version because it's unlocked. Depends on what you're doing. I haven't read into Haswell too much yet, but with Ivy Bridge the K versions lack features that the non-K has (for example, I do not have PCI passthrough (VT-d) on my 3570K, but I'm not planning on running HyperV or Xen on here so it doesn't matter right now).
