|Not very good with the specs. What's the make/model of the graphics card? 2GB means nothing. It's the GPU & type of memory used on the card that matters. For instance, on cards using the same GPU, 1GB GDDR5/128-bit will mop the floor with 2GB DDR3/64-bit. If you have a 2GB DDR3/64-bit card, try turning down the game settings & game resolution to reduce the lag.|
And telling us you have a 600W PSU means next to nothing. Is it a quality name brand unit or a generic cheapie? Efficiency rating of 80 plus? Single +12v rail of at least 30A? Active PFC?
And lastly, AMD doesn't use a FSB & hasn't in over 10 years ago. It uses the HyperTransport bus. On your system, the HT bus runs at 1000MHz (2000MHz DDR). Assuming you have DDR2-800, the memory bus runs at 400MHz, but that can vary depending on the CPU multiplier.
Anyhow, eMachines/Gateway/Acer (they're one & the same) put the 89W limit on that board for a reason, probably due to the quality of the VRM (voltage regulator module). I can see a 125W CPU being a problem, I'm not sure about a 95W CPU, but it might overload the VRM & fry the board. Also, it might not be properly recognized due the CPU ID data not being included in the BIOS. It's an outdated system anyway so no great loss if it fries, it will give you an excuse to build a decent gaming rig.
