Phenom II X6 1090T (3.2GHz) seems nice at $285
It's a nice CPU for sure, but it won't be the best for Civ4. Five of those cores will be idle; better to buy an Intel part with fewer cores and better performance per clock (and probably a similar clock rate) for the same price.
Fëanor;9137545 said:I found the benchmarks of the two new Phenom II X6 rather unimpressive. The Phenom II X4 955 is still the king of performance per $.
I found them impressive. For the price, you're getting an astounding value, especially the 1055T at $200 for a hexacore. With the $50 rebate, all the better, but even without it, if I were looking for the most raw power per dollar (and were assuming I could take advantage of all the cores), I'd go for the 1055T.
Lower-end, the 2.7 GHz Tri-Core at $70 from AMD is also excellent in performance per $, as are the lower-end quad-cores.
Sorry, I mixed the two numbers there, I meant the new i5-680, which has only two cores, but 3.6 GHz, which is the highest of all the cpus, so it should be best for Civ4, right? And probably Civ5, too.
Most likely, yes, that will be the best CPU for Civ4. For Civ5, it won't be, as Civ5 will support more cores.
There is a slight chance that an older CPU will work better for Civ4. I know for Civ3, the cache size of the CPU apparently had a large impact on performance (I've never been able to test this myself, due to lack of sufficient hardware resources). Thus, it is possible that the 3.33 GHz Core 2 Duo E8600, with 3 MB of L2 cache per core instead of the 512 KB of L2 cache plus 2 MB of slower L3 cache per core of the i5-680, would actually perform better at Civ3, and possibly Civ4 as well (I know less of what impacts Civ4's performance at the CPU level).
Many synthetic benchmarks don't depend much on cache size, but I have seen some benchmarks where the older Q9550 (2.83 GHz, 3 MB L2 cache per core) beats the newer i7-860 (2.8 GHz, 256 MB L2 cache per core plus 2 MB of slower L3 cache) due to its larger L2 cache. If this would hold true for Civ, the Xeon X5270, which is essentially the E8600 but clocked at 3.5 GHz, would likely be the best CPU for Civ4.
It's even possible that the old Xeon 7150N, based on the Pentium D, would be best for Civ3 or Civ4, due to its gigantic 8MB of L3 cache per core, and 3.5 GHz clock rate. I doubt it, but T.A. Jones used to swear that Civ3 ran considerably better on a Cedar Mill Pentium 4 with twice the cache of a Prescott, so I won't rule it out.
Okay, but you know, I play only civ and manager games - do I need to care about FPS?
So maybe IGP will be enough for me? Or a little card like HD5670 or even HD5570?
For Civ4, you'll be fine with any current-generation IGP. For Civ5, I think it's too early for any of us to know for sure.
