Hello, I currently have an AMD Kuma 7750 overclocked to 3.2Ghz. I am using 4 gigs of DDR2 memory capable of running at 1066 however I am running it at 800Mhz 5-5-5-15 timing as the general consensus seems to be there is no noticeable speed difference at 1066 with looser timing. I would like to upgrade my machine in anticipation of IL-2 Cliffs of Dover. I was considering upgrading my processor to a Phenom II 840 for around a $100 which has 2 more cores then the Kuma however lacks the L3 cache. Since both processors would be running at the same frequency I was wondering if this upgrade would be worth it. My current AM2+ motherboard will support AM3 processors but only up to 95W and I believe the 840 is the highest end quad core I can get with 95W.
The Kuma has 2 cores, 2 megs of 32way L3 while the 840 have 4 cores and no L3. Now I am fairly sure that the 840 will smoke the Kuma in multithreaded applications but I am wondering if I should expect any slowdown on older games like Unreal 3 or Dirt 2 for example. I am also concerned about single threaded applications like the original IL-2 Sturmovik. Keeping in mind both processors will be running the same frequency. I am also considering getting the fastest 95W AM2 quad I can get but don't really know what that would be and if they are even available anymore. I would prefer at this point to probably not get a whole new MB, Mem and processor. Thanks for any advice you can give. I will also be upgrading my video card to probably a GTX 560 ti in the next few weeks from my old 4830 card.
