Hi, I am planning to build a mid-range computer but I cant decide whether I should go with AMD or Intel. The computer will not have a specific use (IE gaming etc) but I would like a reasonably fast computer that will be good for a few years use. I have been looking at the AMD sempron (2800 or 3300) and the Intel Celeron 2.80 ghz. Could someone tell me a few things (such as the L2 cache, is that important - on the celeron it is 256kb is that ok? And If the processor is 64 bit enabled, can I still use it as a normal procesor (with windows xp 32 bit? And finally, can someone give me an idea of how the above processors compare as far as general speed is concerned?? For example, I currently have a P4 3ghz 512mb ram... and I find this PC very fast - how would the above processors compare to this spec? PS the machine I am building is for someone else by the way... Any help will be much appreciated. Thanks in advance.
