i got aN intel i920 CPU
i was considering upgrading MY GRAPHICS to RADEON 7870

  1. Your CPU should be fine for pretty much all games, you may see a slight performance increase in some games if you overclocked the CPU alitttle due to the 920's relatively low stock clock speed (2.66Ghz) However I'm sure you'll get playable framerates in all games even at stock.
  2. You mean the i7 920? It will be plenty for a 7870 in most games. Extreme cases like hectic firefights in BF3 multiplayer will bog it down, but in general it won't be an issue. Most games don't need very much CPU power, and any old quad core will do, or even a good dual core from the last year or so.

    My old Xeon X3210 wasn't slow enough to bottlneck most games, even at its stock speed of 2.13 GHz.
  3. It shouldn't bottleneck, but consider overclocking when you feel it is bottlenecking.

    yeah most games your sit, some rts games my cuase a slow down but nothing manageable

    wow willard, is that your everyday clock speed
  5. Nah, that's by benching speed (if you're referring to my 2500k @ 5.25). I run it anywhere between 4.5 GHz and 5.1 depending on what I'm doing. 5.25 is way too hot for 24/7, and takes a lot of voltage.

    Got it stable as dual core at 5.35 GHz, but that's useless for anything but a few benches like SuperPi. My goal is 5.3 GHz stable with all four cores active, but keep hitting a brick wall at 5.25 no matter what I do. Need watercooling so I can crank up the voltage some more.
