fx-51 or 3800?

[brack]

from what i have heard or what i thought i heard. the athlon 64 fx-51 and 3800 are supposed to perform the same because the 3800 has a 2.4 ghz but 512 L2 Cache and the fx-51 has has a 2.2ghz and 1mb l2 cache. Is it true that they perform equally? if not which one runs better? i think i want the fx-51 cause i could easily oc it to 2.4 ghz even higher

I thought the FX-51 was 2.2ghz, 1mb L2 cache with dual channel? The FX-53 is 2.4 I think. Theres the 3700+(socket 754) thats 2.4ghz 1mb L2 cache, but no dual channel. Theres teh 3800+(939) 512k L2 cache, with dual channel. The FX just takes in the best of both and unlocks multipliers.

The 51 is an Opteron 148 for Socket 940.

Socket 940 mobos are not exactly favorably comparable to Socket 939s.

3500+ for Socket 939 is really the only choice if you don't wish to go for Socket 754s because it costs hundreds of $ less...


If $ is no object, then it's the FX 53 (939, not the 940) or the 3800+....

If cost is not a concern at all, get the FX-53.

For building cheapest 939 dual channel system, get the 3500+.

the fx-51 is inferior to the 3800+. The Fx51 is about a 3500+ in performance.

The fx series multiplier being unlocked is definetly a good thing...........illd buy 939 though. Havin to use registered ram gets expensive(trust me)
