They both have the same specs but the only difference is the second one has a Intel Core 2 Duo P8400(2.26GHz) while the GX630 has a AMD Athlon X2 QL-62(2.00GHz). The GX620 also comes with a Vista home premium CD, while people say the GX630 doesn't, so that is like $300 for the CD, as I reformat sometimes.
In conclusion, is it worth paying about $180 more for a better processor and the CD? Will the Intel processor give better performance? Not just a couple FPS.
I'm currently thinking about going for the GX620 as it has a better processor and the CD comes with it. I don't mind paying a bit more, but I want your opinions. I also like the GX620's design better.
