I just looked up the Bulldozer CPU, and I am wondering: Is it supposed to be an 8 core? Or another generation of 6 cores? And is there any confirmed price?
at this time, it is said that bulldozer will have 8 and 4 core variants. it is a completely new design from the ground up, comprised of 2-core nodes (so conceivably they could release 2- and 6- core variants) the current phenom ii processors are ultimately derivatives from the original athlon 64 cpu's, which, iirc, were restructures of the athlon xp cpu's...i could be wrong on that last point though, i'm sure someone will correct me if that is the case.
i don't know what you mean by athlons being "long gone". an athlon ii cpu is nearly identical to a phenom ii, the only difference being the athlon ii doesn't have L3 cache, but this is a relatively minimal difference. as i said, i've owned an athlon ii x3 (2.9ghz, oc'ed to 3.3), and i presently own a phenom ii x3 (unlocked to a fully functional phenom ii x4 and oc'ed to 3.2ghz). i don't game much, but i do game at 1680x1050, a substantially higher resolution than you, and i do a good bit of multitasking other than that but nothing individually that's too demanding...for you i truly believe that the athlon ii x3 will be a great processor.
let me put it this way, there are 2 ways to look at it.
1. you're coming from a p4, so anything modern will be a substantial upgrade...i'm sure you remember how the athlon 64's more or less trounced their p4 equivalents? the athlon ii x3 is a triple core version of a much updated version of the athlon 64. so...yeah.
even though the phenom ii x4 would be faster, you would still be very satisfied with the athlon ii x3, but on the performance end of perspective (rather than the value end)
2. why drop $300 on a dead platform now, when, if you really think that the phenom ii x4 will be that much faster than an athlon ii x3, which it won't, you can get something to "tide you over" (which, again, will completely decimate your p4 rig) until bulldozer comes out, which will show a much larger discrepancy between itself and the phenom ii x4 than that between the phenom and the athlon?
so, the way i see it, whether your goal is value or performance, it simply does not make sense to drop that kind of cash on a phenom ii x4. and, who knows? you very well may be totally satisfied with the athlon, and you could just use that extra $ you saved to buy a nice ssd (i'd take athlon ii + ssd over phenom ii + hdd any day), or just pocket it!
