While I see your point about upgradability but its kinda futile to upgrade an AMD setup at all. First, lets dispell the myth that semprons suck. I put two computers together for two friends. The higher end one is a A64 3000 Winnie, Abit mobo, 1GB of performance RAM, and a 6800GT (AGP). The second one is a Sempron 2800 (OC'D to 1.8ghz), biostar Tforce board, 1GB of mismatched RAM, and a 6800GS. Both of these morons love playing BF2. I wont go into details of specific graphics settings, but they play the same. I think the first set up runs a little smoother and loads up games a little faster but it cost $799 for the components listed above. The sempron was $397. I can attest that there is not $400 worth of difference between them. In short, the A64 setup is not so much better that the resolution and eye candy can but turned up s much higher that you cream your self or say something like, "damn, i sure am glad I got this A64 instead of that damned sempron. Yes, the A64 set up is better. But not $400 better. Yes, the A64 set up can be upgraded, but why? Why buy another chip when you can OC to whatever you need? Lets say we can only get that A64 3000 to 2.2 ghz. Is it worth another $300 bucks just to get a A64 3800? Will the extra 200mhz really make a difference? yes, its sucks that the Sempron is based off of dead end tech. but that dead end tech is still better than any celeron and many P4 setups and is within the realm of a lower end A64 setup. And it is so cheap too. let me put it this way, if you were to buy a sempron setup today, why would it be an issue to buy a new chip for your S754 mobo 9 months from now (even if it were possible)? You would pay say, $150 for a high end S754 that wouldnt even touch a low end AM2 for the same price. here is the reality for us consumers ok? All computers are like BIC razors.... they are meant to be thrown away when you are done using them (except for GPUs). I would gather that if you have a limited budget ($500) or less, you cannot go wrong with a sempron set up. In a few months there will be something new for us to bitch about and then turn around and buy. As for my friends, the A64 holder is pissed that he bought a $180 Abit Guru mobo that wont accept newer PCI-e GPUs like the 7800. he is very reluctant to buy again and is even more pissed that a supposed low end system can touch his. As for the Sempron user, I dont think he is going to be bothered too much by chunking his system when he upgrades. The bottom line is this: both of these chumps are going to have to buy all new core components come next year if they want to upgrade. so I would say the sempron user comes out with the upper hand out of the two. This is just my opinion formed from the "seeing-is-believing" technique.
