Hello, in the past when a new graphics card or CPU came out, you would read reviews from people saying "WOW my system is so fast now!!" However I must be doing something wrong since anytime I upgrade there isnt a huge jaw dropping performance incrase like everyone hypes it up to be. When I upgraded from a Geforce 5700 to a Gefroce 6800 GT I can honestly say that the framerate was the same, the only difference was the 6800 was able to use anti aliasing and keep a fairly better framerate, but it wasnt worth a $400 investment so I took it back. So now for the reason for this topic, right now I have an AMD XP 3000 and thinking about upgrading to an AMD 64 939 pin. I noticed that they both run at 2.2ghz, so how is the 64 able to dramatically increase in speed? I dont want to buy a new mobo and AMD 64 CPU to find out that the speed increase is barely noticable. Thanks

Well obv the major diff between the two is that the AMD Athlon 64 are 64 bit and the AMD Athlon XP are 32 bit. Here are some more differances.... The way the Bus speed is handled are diff. The Sockets are diff. The Architecture is diff. The Processor Instruction Set are diff. The bits on ram are diff. But here is the diff between the AMD Athlon 64 754 and the AMD Athlon 64 939 just alone. Socket 754 vs. 939: Socket 754 CPU: Single Channel Memory only 64bit DDR SDRAM at 100, 133, 166, and 200Mhz Three DIMM's supported 800Mhz Hyper Transport Bus Speed Runs hotter than socket 939 cpu's Consumes more power than socket 939's Socket 939 CPU: Dual Channel Memory 128bit DDR SDRAM at 100, 133, 166, and 200Mhz Four DIMM's supported 1000Mhz Hyper Transport Bus Speed Runs cooler than socket 754 cpu's Consumes less power than socket 754's

Thanks yes I understand the specs, however how does it perform from your perspectful. When I upgrade the hardware lists all types of huge specs and all of the things it can handle, however when you pop it in the computer you only notice a minor increase. If I am going to spend $500+ I want to say "WOW!" not "Ok what's the difference?"

Wow sorry for the typos and bad grammar, I am half dead and havent had any sleep yet. I meant to say "perspective"

If you Think your 5700 is as good as a 6800GT then don't upgrade your are playing old games and performance means nothing to you.

I know it is hard to believe, but I am playing Quake III, UT, Half Life 2, well in short just about every PC game out there and for some odd reason the 6800 GT wasnt a HUGE increase in performance. I can only assume it had to be a driver issue or something, but when I purchased the 6800 GT the performance wasnt all that dramatic. I hope that I did something wrong and will purchase the card later on when I get a new mobo and cpu to see if it will work better then.

Well at the moment if ure pc is fine as it is why bother upgrading. 64 bit means it can double the amount of data a CPU can process per clock cycle. Therefore its faster but if u are gona piss about with word n half life two well you wont see that much different since you have a decent machine anyway. How much better is amd then athlon xp? the potential is a lot, but for playing games n s--- like dat well ure machine is good enough
