Hi guys, I've been thinking about getting an MSI 7850 power edition: http://au.msi.com/product/vga/R7850-Power-Edition-2GD5-...

But then I recently found you need a decent power supply...
This is my current PC: http://h10025.www1.hp.com/ewfrf/wc/document?cc=au&lc=en...

Under power supply it says only 300 watts. Guess i'm spending another hundred bucks for a better power supply <_<.

But anyway, apart from power supply, is there anything else I need to know? Anything else I need to buy?
Will the MSI 7850 power edition acutally fit in my case?

Oh quick edit: Will most 500W power supplies fit in my case as well?
Thank you very much for your time!

You are going to struggle to power that 7850 with that 300w PSU. Are you having problems playing games or something?

Dude seriously with that APU I don't think upgrading to a 7850 is a good idea. Upgrade to a 6850 might be OK but a 7850 I don't think so to be honest with you.

yes you can run it
but you need atleast a quality 450w psu

APU = Auxillary power unit? Is that separate to PSU? So if I buy a 550W psu will it still not work?
I'm just wondering if there would be any problems with buyng a new power supply, and the OC 7850 I posted and putting them in my HP PC (Like if the components are too big, or aren't compatible, ETC)

apu =accelerated processing unit
which in your case is the a8-3800 processor in your rig

Thank you very much for your time panwala, but i'm wondering, with my APU, will getting the 7850 still be better than 6850 performance wise?
Does refillable mean the results will be neglible, or does he just mean the card won't perform at it's best?
Couldn't I upgrade the APU later on if I wanted to?

You can't really upgrade your APU. That socket is dead. The APU will bottleneck a 7850.

What is your resolution? A 7750 would likely be your best option, or a hybrid crossfire option. Something where you don't have to upgrade the PSU.

1980 x 1080
So you think a 7750 would be the best you can get before hitting the "cap" at which the processor cant keep up?
PS: I only have 300W, and it says minimum 400W recommended. Is this a problem?

A8 is still not terrible for low-mid gaming, get a new psu and a ~6850/6870 or 7770 but personally I wouldnt go any higher than that with your current mobo/cpu, that is assuming you buy a new quality psu...



If you dont wanna upgrade the psu, which I recommend doing... get a 5670, itll run on just about any psu...

and by no means are you going to be getting satisfactory gaming at 1080p with either the 7750 or 5670 imo, unless your standards are low... not judging just saying

You can probably go higher that a 7750, but if you do you have to upgrade the PSU, and with that and bottle necking it really hurts your price/performance. Maybe someone else had another thought though.

the 7750 would be fine it's a 55W card. Lots of people are using them in manufacture 300W systems. Nvidia/AMD exaggerate the requirements because they don't want to get blamed if it doesn't work, PSU makers tend to lie, and systems vary a lot.

^yeah 7750 consumes just about nothing so if op have a decent 300w oem unit op is ok, like unskol said...

I would still shoot for something a bit higher than a 7750, id upgrade the psu and go shopping on ebay, or look on the toms deals section of the forum this weekend I scored a gtx 460 1 gig 256-bit gpu (not the crap se or 768mb variant) for 90 w shipping... and there are many deals to be had,

not to mention that the 7750 is a bit of a ripoff price at 115 or whatever it is imo...

shoot ill sell you my antec earthwatts 380w unit i have sitting in the closet for $35 shipped, you can buy a second hand 460 ot 6850 and for a little more then what you would have paid for just the 7750 you could have a fairly capable rig, not to mention one that could actually game well at 1080p, my 2 cents good luck

Hey, thanks jjb. So you think the 7750 isn't all that great?
What if I got an MSI 7770 and a new power supply?
Standard model is 1GHZ, OC model is 1.1GHZ—would that give me good quality 1080P gaming with decent longevity? (and which one would you get in my position?)

yeah you would be getting closer for sure, id get a new psu and try to snag a second hand gtx 560 or 6870 tbh, that will give you the baseline performance your looking for imo...

7770 is a nice card too but personally I'd go for the second hand options mentioned above, of course its your choice but id check out some benchmarks of your favorite games by doing some google-ing and see for yourself...

the msi is certainly a desirable model

Just out of curiosity if I get a 7770 (or another one I dunno)
how long do you think it's going to be before I have to scrap this computer, if I wanted to game reasonably well at 1080p
A year... longer?
Guys i'd like to thank you all very much for your responses.
In a day or two im going to order a graphics card from online, i'm leaning towards the MSI overclocked 7770 atm.

I don't get this computer at all.
Hp put a geforce 520 card in a computer with a A8-3800 apu?

I know it sounds kinda dumb but try taking out the geforce 520 and see if the integrated gpu works. (maybe its some sort of "damaged" oem a8-3800 and the gpu part is actually fried?)

If the integrated gpu works fine, try it out, i think its actually faster than a 520.
The A8-3800 has a 400 shader gpu. It is not great, but its ok.

http://www.amd.com/us/products/technologies/dual-graphi...

A hd-6570 is fairly cheap, the two kinda add up to a single hd-6770.

The A8 is not as bad as you think, but on the package hp you cant overclock it,
2.4ghz really kills it.

I am running two hd-4870's with a A6-3650@3.5ghz. It does well in gaming, but at it's stock 2.6ghz clock its pretty slow. Simply put that extra 900mhz and faster blck clock does help alot.

OP

there is no telling how long you will competently game at 1080p 7770 is a decent card but no speed demon, id recommend getting something better

there are a lot of options to ponder but you gotta be comfortable spending an amount so ultimately its up to you, look at benches and make a choice now that you are empowered with a little knowledge

If the A8-3800 tests out ok running the integrated gpu, maybe a new board would help more?

I am running a Gigabyte GA-A75M-UD2H its a micro atx board but has crossfire slots and a pci slot in the right spot to add a sound card like a x-fi pci.
Blck overclocking should get you to 3.3ghz with a new cooler and some case fans.
The gpu should clock to 800mhz or higher too. Or a new ps+ used pair of hd-4870's, 5770's/6770's, or single larger card.

if you do buy a new board, stick with gigabyte, asus FM1 boards are not known to overclock the blck clock so much. (i set up another system with a asus board but luckily it was a a8-3870k).

Anyways for some reason 1.45volts 135 blck, and setting the memory to ddr3-1066 with ddr3-1333 or 1600 spd timings should get you there.

There would be a issue with the oem os system not liking the board swap too.

there is a good chance if you google it, there is a modded bios that unlocks some features like blck clock and voltages too on the hp board.

http://www.overclock.net/t/1177093/stuk-in-hp-hell

It sounds like its a ecs board.. if you manage to find the retail ecs bios, fsb overclocking sounds like it could be possible.

YES YOU CAN KILL YOUR BOARD SO BE CAREFUL!!!!

=( I'm so confused now though =(
I originally had my heart set on spending about 250-270 dollars on a 7850, but then I asked in this thread and people said it would be pointless.
I know you think second hand cards are a good idea, but I live in Australia and I have no idea where I could get a trustworthy one.
Guys thanks very much for your responses, i'm going to bed now and will check the thread tomorrow :) 
Oh one more thing—what about http://www.megabuy.com.au/gainward-gtx560-se-1g-1024-mb...
That's probobly better than the 7770 right?
Edit: People say it stands for "Suck edition" and that the 7770 is better O_o

Thanks guys I've come to the ultimate conclusion that I might have to wait a couple of years (when I custom build my own PC) to get all the high performance shiny stuff I wanted :) .
I think ill get the OC'd MSI 7770 and a new power supply.
When the PC gets old, ill start dabbling with overclocking if need be and try to kick that HP setup's arse :p
