[citation][nom]mforce2[/nom]You can still find plenty of new generation Radeon cards for AGP so it shouldn't really be a problem. Anyway I don't really see anybody installing 7 on a 1 GHz CPU. Well except maybe for netbooks , those 1.6 GHz Atoms aren't really much more capable than a 1 GHz P 3. Not to mention the quality graphics found on those netbook IGPs , the 945 really is as crappy as you can get. If you think about it though these requirements are way too high. Sure the new and even some older PCs don't have a problem with these specs but let's not forget what we're talking about here. 1 GB of RAM , that's like 1 GB = 1024 MB , a 1 GHz CPU , 16 GB of space on the hard drive , and that's just for the OS. I remember having my first PC with 16 MB of RAM , a 133 MHz CPU and you know what , it managed to run Windows 95 just fine. I can accept times have changed , that Windows 7 is way more advanced , that it has Aero and so on ... But still , maybe 512 MB , a 500 MHz CPU and 8 GB of storage would have been enough. I do have a Linux PC that runs pretty well on that and it's using the latest KDE GUI , a new kernel , not something from 2000 like Windows XP.[/citation]
Well, actually the Atom does have some advantage. Unless you're talking about the P3 Tualatin, that has 512KB L2 Cache, which was rare on desktops, though you can find them in laptops, the all other P3's, including the normal Tualatins only had 256KB L2. And then you have to consider that the Atom has support for SSE2, and SSE3 which is a plus. And then there is the platform. The Atom has a 533 FSB compared to a 133 for the latest P3's. And P3's generally had PC133 RAM, compared to 533Mhz DDR2 or even 667Mhz for the netbook platform. So I'd say the Atoms are generally better suited.
I'd keep a P3 for a Windows XP or a Linux based Media Center. I have a P3 at 1Ghz with a 26W TDP, which is still pretty good by today's standards (those were efficient processors.. then came the P4... and fortunately then Intel went back to the gold old architecture 😀)
