im not sure weather to get a 5770 or a 4850 but there are limitations

my specs unknown at time cause upgrading atm
so far going
from to reason
CPU: P4 640 3.2ghz q8400 quad 2.66ghz perfromance
Mb:81915pc duo sis's 946gmx-s2 81915 is only 800mhz 946gmx is 1066mhz
ram:512mb ddr2 533mhz 1gb ddr2 667mhz with mobo
GPU:x300se 4850 or 5770 performance
cooler: ocz vendetta 2 silent cooling
case: CM case recycle
PSU: CM 380w 16A 12v sun pro 550w 380w only has 1 4pin line. 550w has two lines for the six pin adapter
mon:19"1280*1204 22 1680*1050

i realise that the power supply is a no name brand it but it was either the cm or this and i dont think the cm is going to work.
my question is either to get a 4850 or 5770/50
also is dx11 a major change?

5770 is an equal to a 4870, both will be much better than a 4850.

Make sure you motherboard can support a quadcore. A pentium 4 motherboard is usually very old and might not support quads or 45nm cpus.

This Corsair PSU is good and only $30 after rebate.

The HD 5750 matches up against the HD 4850, while the HD 5770 is more like the HD 4870 performance wise. In either case those cards uses less power than the HD 4850 so going HD 57xxx means you do not need to worry about upgrading your generic PSU.

The 5770 is easily the better choice and fit to the system in my opinion

the manual say it supports 1066 fsbs.

also could you recommend a cheap low power modular psu? as a backup it the case that psu dies

Definitely go for the Rad 5770, not only its much faster than 4850 and a lil'
faster than 4870 but It supports DX11, Shader 5 and DC11 which will give you
better gaming experience and performance while playing those demanding games
specially games that supports DX 11. Also, it provides better overclocking
performance than 4850 and consumes less power. Though a lil' pricey than 4850
but its price is worth its performance, guaranteed!

When it comes to cheap modular PSU's, it ranges from 600 watts and above if
you're looking for a modular one under 500 watts, you'll gonna have a hard time
looking and if there's one, chances are its not P80 certified and the quality is
not as those offered by well known ones.

Tom's November card recommendation says that the 5770 is a little slower than the 4870 in most instances. However, with the lower power consumption and heat, the 5770 is still a good choice.

I manage to oc my 5770 to 950/1450 and get awsome performance, i swapped it out for a 4870!!not looking back. My mate just got a 5870 and his card aint 2x as fast!!!(which it was meant to be)

Im just looking for a second 5770 for xmas!! deffo the better choice!!

I also ran Heaven Benchmark with tessellation and it looked awsome, so get a 5770 now, n when it starts to get stressed, get another and CF!

FSB has nothing to do with cpu support.

The motherboard needs to be able to support 65nm quad cores for Q6x00 series or 45nm quad cores for Q8x00 series and above. There should be compatibility lists if you google the motherboard's compatibility specs, or check intel's website.

Also, some motherboards require special BIOS updates for the newer 45nm series as well.
