my rig is athlon 7750 dual core oc to 3ghz .motherboard is m3n78-em.2gb ddr2 ram at 800mhz.psu is fsp saga II 350w dual +12v rail at 16a max output on +12v rail is 305w..max power is 400w.
i am planning to buy ati 5770 radeon 1gb...my monitor is 20 inch with native resolution at 1600*900.
my question is there any bottleneck with my system..?will 5770 fit in my motherboard...?i mean the size not pci express slot issues.is my psu ok...for max overclock..?will 5770 run all games at 1600*900 maxed out settings with full AA?which to compare stock 5770 to..max oced 5770 to?

i'm not really sure about your processor but if you suspect it will bottleneck your card then OC your cpu. about your mobo i don't think you should worry about it but instead you should worry about your case. however 5770 is quite a short card so it should fit really well in any standard ATX case. at the resolution you're going to play at 5770 should have no trouble maxing out any games out there (with AA enable) except Crysis :D

fsp is a good PSU maker but to be honest i'm not really sure if the PSU will be able to run 5770. in their site amd recommending 450w psu to be used with the card but i know some people able to run the card with 380w psu

performance based 5770 is definitely better than 4850. based on raw performance 5770 is near to 4870 or 260. the one that comparable to 4850 is 5750 or 250 for nvidia cards :) 

Personally i have never heard of your PSU brand so i would not try to overclock the card until you try to buy a decent PSU. Generic or no name PSU's have the tendency to fail even at 75% of their max usage. Don't push it too much.

Well it says on the side of it and you already posted what it can do in your first post. You should try saving some money for a new PSU after the card gets to you. The PSU is the most important component inside your PC because it runs everything.

I would not think of overclocking with that PSu, you could fry your PC. Hope it holds with the card stock.

ok thanks...:-)which model to select in msi 5770 pm2d1g-oc,pm2d1g,hawk,pmd1g...?i know hawk is good...?but for wat reasons?its not in stores now...if i have to pick other than hawk...wat model would be best....?

Post here the links with the models you chose and we will be able to help you chose one.
XFX, Sapphire, Sapphire vapor-x, Gigabyte..etc. The ones i named are good brands.

Because there are 2 types of video cards that have air cooling, the ones that evacuate air out of the case and the ones that evacuate air inside the case. That is why i want to see your case.(hope you understand what i meant)

from what i remember its a standard atx case...i have ordered my 5770 its msi pm2d1g model...rest of models are not available...:-( will get my 5770 2mrw....i will post the picture of my cabinet coming saturday when i go home....is pm2d1g model ok for oc...? what is the max core clock i can reach with this model...?

i got my 5770....:-) its actually msi pmd1g 5770....:-) its good right for oc it supports msi afterburner voltage control...:-)cant wait to go home to install it...:-) any comments about this pmd1g model...?

Here, i am :) ). I did not have the time to stay on here. Ok, install it and do not overclock it.

Do you have any fans for intake and exhaust installed? The video card does not exhaust the air outside the case and could get a little hot if your case does not have good ventilation. Worst case when you are gaming remove the side panel.

As i said, do not overclock, i do not even know if your PSU can handle it and i do not want to see your PC fried:( .
Also read the instructions manual on how to install your card.

will put the picture..on saturday when i go home...ok i wont oc...i dont have any exhausts...yes my side panel is always open...is pmd1g model good compared to reference model..? i heard that the fan is inefficient...? it heats up a lot....?

After you install it and if it works on your power supply then install the latest drivers from msi site and use catalyst to increase the fan speed to 40% when not gaming.
When you are gaming increase it to 60-70%, depending on how much noise you can tolerate.
You should have gone for the model that you first posted here because it was better. If you got it from a store near you see if they can change it. Hope the price is the same, if not will do fine.

ok...but that is the only available model..but this has overvoltage function...so i thought this would be good along with the big fan...for cooling...my bad....:-( ok will try to the shop one more time..

If you can not afford that and do not have the option for a refund and buy another model from another store then keep it.
XFX would give you double life time warranty meaning that if you sell it the new owner will also have warranty.

Well heat and noise..

Pros, great video card and msi make's pretty good components from what i know.

Well for the 5770 i say to keep it under ~75, that would be great.

I got mine to max 73C wile overclocked witch is weird because it is a vapor-x version and it should stay cooler. Fan was at 70%. At 100% fan it won't reach 70 in any game no matter what i do but the fan is loud.

Not all games stress the video card the same. When i play Call of Duty 6 i get around 65-68C, in Burnout Paradise i get 63-65, in crysis i get to ~70C, in metro 2033 the same.

C - Celsius

From reviews on newegg it get's a little hot. As long as you keep the case opened it should be fine under 80C.

I won't tell you because you will overclock your card then..ha ha ha..

When you get a new case with one front fan for intake and one fan that is at the rear for exhaust and a new power supply then i will tell you.

Even more in India is pretty hot now.

Right...i did not overclocked my card eider to see what it can..ha ha ha.
You can see in my review.

It's your responsibility anyway so do as you please. I do not think that you PSU can even power it let alone with an overclock.
