Ok. Following is a description of my hardware addiction:
The AMD chips I currently have in my possession are: X2 3600+, 4000+, 5000+ BE, Phenom 8450, and Phenom 9950.
The intel chips I currently have in my possession are: (had) E2180, E5200, E7200, E8400, Q6600.
For AMD mobos I have a Biostar Tforce550, and Biostar 790GX. For intel, Gigabyte P35 DS3L, and MSI X48 (dead).
I have three different sets of DDR2 800 memory. One G.Skill 2x2Gb, one Corsair XMS 2x1Gb, and one Kingston value 2x1Gb.
For GPU's I have (had) an evga GTX 260 core 216, (had) Visiontek 4850, (had) Visiontek 4870 512, and my current card, Powercolor 4870.
I have played with nearly every conceivable configuration of this hardware, and the "cleanest" or "smoothest" (evidently BS from what I hear) running setup out of them all has been my 790GX/9950/4870 combo. That means least stuttering, best framerate stability, least crashes (stock or OC), least trouble with driver errors, least trouble with hardware changes.
Why is this?
Could be:
1. Mobo peculiarities
2. Ram peculiarities
3. Defective CPU's (umm not likely)
4. An all AMD platform runs better (dunno, maybe)
5. Luck of the draw?
I prefer my Phenom/790GX over my Q6600/P35 in gaming, whether stock or OC'ed. It just seems to run games smoother. Although the average framerate is lower, I seem to get better framerate stability.
Some may say I am imagining it or spouting BS, but I most certainly do not feel that I am.
I am not necessarily saying that AMD or intel is "better" for gaming, all I am saying is "Here is the hardware I have, and here is what I consider to run the best out of the hardware I currently possess"
The funny thing is that I am not the only person I have seen have the same experience, so either we are all imagining it, or there is something going on that can't easily be shown with benchmarks and graphs.
