I'm having some issues with my current NVIDIA GeForce 8800 GT adapter. I am not too savy when it comes to internal computer components and would like some recommendations for a replacement.
The computer is used for mostly AutoCAD work. I would like to keep the same or better performance without spending a ton.

-ASUS M2N32-SLI Deluxe
-AMD Athlon 64 X2 Dual Core Processor 6400+
-Windows XP
-3.21 GHz, 3.50 GB of RAM
-550W PSU

Any guidance is greatly appreciated.

anything newer will be better... 9800gt/gts/gtx, gtx260/265/280, 460/470/480 any of these can be bought on ebay for $50 to $75.

I'd get a gtx460 for $60ish used and there you go

A GTX650 would be a good replacement IMHO.

If Autocad behaves anything like other professional applications,
one would be better off replacing the 8800GT with a Quadro card; even
an older 1GB Quadro 600 demolishes most modern gamer cards
for most pro apps. See my benchmark results here:

However, from results I've found on toms, it looks like Autocad can
run quite well with a good gamer card, which makes Autocad one
of the more unusual pro apps in how it behaves (Ensight being the
other example).

Note that as with most pro apps, the power of the main CPU can
also be a limiting factor, as shown by the Pentium G840 + Quadro
4000 results I added to my page today; notice how in some cases
performance is nowhere near as good as the same Quadro 4K
running with a 2700K. ProE, LW and SW inparticular benefit from
a strong main CPU (especially ProE, which I've been told is only
single-threaded, so a high-clock dual-core is a good low cost
option for ProE), and also Maya to a degree.

As such, with a more powerful GPU for Autocad, you may find
your main CPU holds back potential performance.

As it happens, your system is remarkably similar to a PC I built
for myself a few years ago; it had a 3.25GHz 6000+, ASUS M2N32
WS Professional, Gigabyte 8800GT, 4GB RAM, etc. (I added a
second 8800GT later), See:

After I discovered it wasn't possible to fit the mbd with a Phenom II
CPU (no BIOS support), I switched to a P55 setup with an i7 870.
The performance increase from even one 8800GT was considerable,
though this was for games please note. Later I upgraded to GTX
460 SLI, and so on. Meanwhile, I started collecting Quadro cards
and other gamer cards to run comparisons (I have more than 40
GPUs now, ditto combinations of mbd/CPU). Today my gaming PC
has two GTX 580 SLI.

Thus, whatever GPU you obtain, bare in mind that you might observe
a larger performance increase by pairing your purchase with a better
CPU. It depends on the degree to which Autocad is sensitive to CPU
performance (I don't know).

If you'd like me to test anything specific for you, I'd be happy to
help. I have a 3.4GHz 6000+ setup which atm has two GTX 460s
fitted, but I can put on an 8000GT instead to get a baseline
score, then I can fit other cards to compare.

I have been Googling the possibility of running an Autocad benchmark
for you. Have you seen this site?

Please PM/email to discuss Cadalyst further if you wish.


PS. To the other posters: replacing a gamer card with yet another
gamer card when the OP is running a professional application may
very well be completely the wrong thing to do in terms of the best
buying decision. The OP is not playing a game. Best to find example
performance data before making a recommendation where a pro
app is concerned. I'm hunting atm...

Just found these:

so it looks like Autocad can indeed run quite well on a decent gamer card, assuming
the CPU isn't a bottleneck.

dmaximob, is your budget high enough to get a used GTX 580? I've been obtaining a
fair few of those recently for CUDA research, they're available for good prices these days,
though they do need a decent PSU to run.


PS. lowriderflow's suggestion of a GTX 460 is a good low-cost used option. Indeed, in
the same price range these days on eBay, one can get GTX 560Ti cards. Don't bother
with a standard 560 unless it has a high default clock - many 560s were actually slower
than the later top-end 460s, but the 560Ti is a decent step up, especially those with
base clocks of 900 or more.
