Certainly wouldn't be short of space in there! I've always liked compact cases, but thats just my preference ;-)

Emulating might be faster than the real thing, but you will never be able to play ecs/aga games with as smooth gfx as the real thing, due to the missing custom chipset.

Nonsense.

Both screenmodes are "Pal, HiRes Laced" and at 256 colors. The amiga was an A1200,
'060/66 MHz, running a heavily patched OS3.9. This was one of my best runs when
experimenting with various patches and using P96Speed as my testbed. Essentially,
about the best you'll achieve with "real" 68k and AGA. The PC is an Athlon XP-M/2.4 GHz,
Win98SE (bleh) and WinUAE with JIT enabled, a clean 3.9 install and no patches. (I haven't really
fiddled with it much (yet) so eventually it should benchmark a little quicker.) Anyhow, it's
obvious how well WinUAE can handle AGA chipset emulation.

For processor emulation, The SysSpeed "CPU" test returned over 1700 mips and around 850 mflops,
whilst the '060 would crack out about 90 mips and 35 mflops (IIRC).

Smoothness? It seems to me that games or demos which ran smooth on my "real" amiga
perform equally well emulated. Demos which had somewhat choppy effects on my '060 are still choppy
with WinUAE. In "side by side" comparisons, the only real distinction is that certain things (like the intro to
Nexus7) just look better on a 1084. (And I suppose you could run one of these to your 1084, if you
really wanted to...)

The only exception I can think of, is that, mysteriously, a select few demos don't run properly without
the frameskip set up a notch...in those cases a "real" amiga can appear "smoother", but the differences
are subtle and not easy to pick out.

Overall, I would say to someone exploring "the classics" NOT to spend a bunch of money on old amiga
hardware, unless you're into collecting, or seriously waxing nostalgic. WinUAE is cheaper, signifigantly
faster and infinately more flexibile.

Plus...who wants to bring a chick back to the house with a bunch of old 1200s laying around everywhere??
I sure as hell don't...so WinUAE gets an added "two thumbs" for stealthing my more...uh...not-so-attractive
hobbies:-P

Wow!
Great thread guys. THanks for the advice. Looks like I'm leaning on an Athlon Xp 2ghz+ and Asus MB setup...  (With Windoze 2000 Pro - or Win XP? which do you all think is better?)

Anyone have Amithlon second hand for sale (please PM me)

I'll be trying out Amiga Forever 6 :-)

Any websites you guys can recommend for tips/tricks with these programs?

I am using my copy of winUAE with an AMD64 laptop and with Windows XP 64-bit edition. It runs great, much faster than it did under 32 bit windows XP.. I won't post benchmarks because the OS is still under free beta testing and won't see OEM launch until early next year. But you can get a free copy on Microsoft's website.. Now if they'd just make a 64-bit version of winUAE (so I wouldn't have to run the 32 bit app in 64 bit mode)..

If you are a WinUAE developer and you say "BUT! there are no 64 bit apps", have you tried POV-RAY it's already ported to 64-bit..

What do you want to do?   If all you're looking for is a platform for WinUAE, go for Win2k.  If there's anything you'd like to do with multimedia (or anything else) on the "PC side" of the system, go with XP.

Dude :-P

If you're looking to build an oldschool athlon on a budget...get yourself a mobile 2600+ chip
(they're around $100 at newegg), overclock it to 2.4 GHz and 200/400 MHz FSB, then sit
back and enjoy...plenty fast for games and emulators like WinUAE. Just make sure to take
the usual overclocking precautions, research a little, use adequate case/CPU cooling and
decent RAM...blah blah etc.

The Asus nforce boards are allright, but if "I had to do it again" I'd get an ABIT NF7..

just "MHO"
