the site below says that my AMD Sempron 3500+ processor is 64-bit but can any one tell me if its right cuz i wan to insall WinXP 64bit so i can use this software i got http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2207345

Yes your AMD processor is 64bit. AMD doesn't produce anymore 32bit processors. All processors made on the AM2/socket 939 platforms are 64bit. I would say the same for Socket 754, but the the Semperon 3100+ on the Paris core was the only 32bit processor made on socket 754.

1. don't buy from TigerDirect 2. if you buy a Sempron64, do NOT buy one with 128k L2 cache! 3. wait a couple of weeks to buy a CPU. AMD is going to slash prices by the end of the month 3. if you must buy a CPU now, why get a Sempron64 when you can get a full-blown Athlon64 cheaper? http://www.newegg.com/Product/Product.asp?Item=N82E16819103637 http://www.newegg.com/Product/Product.asp?Item=N82E16819103633

Tigerdirect is a huge rip-off. My is (This a joke?) topic explains why. AMD Athlon 64 X2 4600+ OC 2.7ghz 2GB Dual Channel DDR 3200 Nvidia 7900GT SATA II 2x 200gig 7200rpm 16mb cache RAID-0 Gigabyte Nforce 4 SLI

the processor came in my PC i just was looking to see how fast it ran then i found out it was 64 bit but i didnt think it was because the computer was only $239.00. So i spent thousands of $ on PC with Pentium 4 ht processors are they 64 bit?

Not all are any pentium 4 that states it's a EM64T is 64bit. AMD Athlon 64 X2 4600+ OC 2.7ghz 2GB Dual Channel DDR 3200 Nvidia 7900GT SATA II 2x 200gig 7200rpm 16mb cache RAID-0 Gigabyte Nforce 4 SLI
