I have an ATI Radeon HD 4650 1 GB PCIE (DDR2). I wanted to replace the card with something better but still cheap. What would be better An ATI Radeon 3850 1GB (DDR2) or a Sapphire Radeon 5670 512 MB (DDR5)??? would these cards make a big performance boost??

the 5670 would be the better choice. it will be an improvement, but you wont be maxing out your games.

Or an ATI Radeon 4850 1GB (DDR3)

4850 is the most powerful card you've listed so far. What power supply do are you using?
July 11, 2010 9:05:22 AM

My Computer Came with a FSP 300 - 60THA(1) only 300W i know.... not even enough for the 4650. My computer came with the 4650 and the 300W power supply so i think its alright for the moment..... I am going to try a "Speed 600w ATX Dual Fan Switching Power Supply 20/24 Pin 6xIDE 2xSATA New" so that should be good enough for any card i get..... if it fits into my case...

no, dont get that PSU.

the PSU is the most important component in a system, and not the place to skimp. get a corsair PSU, it will save you in the long run i assure you.

+1 Dual fan PSUs aren't usually a good idea. 1 large fan (like 120mm size) is usually a better (and quieter) option.
What other PSUs can you get your hands on? Even a high quality 400W PSU should be enough, 450-500W quality PSU is better.
July 11, 2010 9:35:13 AM

OK thanks i will consider it but this power supply is only about 50$! a corsair cost like 200$ at least. I am planing on upgrading my computer some more but for now im just trying to get it as powerfull as possible so i can save up and build a custom gaming computer.

The HD 4850 is from China and it looks different from the other ones ive seen... would it be incompatable with an American Computer?

not true:

less than 50 bucks after rebate. and plenty for the GPU you are looking at.

we are not telling you this for no reason, the PSU could easily break, and take any other part of your system with it in a puff of smoke.

don't skimp on a psu. it will cost you in the long run.

Definately go for a decent new PSU if you upgrade your graphics card.

Have you considered an Nvidia? Or are you dead set on an ATI?

That motherboard in the "American Computer" probably came from either Mainland China or Taiwan. It probably looks different because of the cooling solution, but they are both PCIe-X16 parts.

I have considerede Nvidia..... but i think i wonna stick to ATI. my computer is all AMD so i think it would be best to stick with ATI to avoid compatability issues.

THANKS! for the link im going to buy that one.... I found a cheap XFX Radeon 4850 for 70$ so im going to invest in a good PSU!

happy to help. a good PSU is the most important part of a system.
July 21, 2010 6:30:35 PM

Im not sure if that PSU would fit into my system! i have a DX-4300. Does the PSU Support XFX Radeon 4850? my case is kinda small so im not sure.... Could someone help me find out if the PSU will be compatible with me computer?

it will support the GPU, the only problem may be the case.

if the case is standard ATX spec then it will fit, but it may be a smaller one.

if the orignal PSU is ATX you will have no issues. otherwise you are a bit stuck.
July 22, 2010 1:49:34 AM

No I dont think its ATX, Its a FSP300 60tha(1). So instead of ATX what kind of power supply should i be looking for???
July 22, 2010 2:33:03 AM

OMFG I JUST TRIED TO BUY THE POWER SUPPPLY! BUT NEWEGG DOESNT SHIP INTERNATIONALLY I LIVE IN CANADA SO I DONT THINK THEY WILL SHIP IT!!!

July 22, 2010 3:17:43 AM

oh, didn't realise you were in canada. try newegg.ca

not sure about pricing over there though.

but if you have a non ATX spec PSU then it wont fit, and to be honest you are very limited. this is one of the main reason we never suggest these pre-built systems.
July 22, 2010 4:03:01 AM

Thanks for the help! I have been looking for a while and I'm about 80% sure that my power supply is ATX spec.

You can also try NCIX.com, Tigerdirect.ca and canadacomputers.com. I usually shop at all 3 and buy a part I want from the one that has it for the cheapest. Or I pricematch on NCIX.com.

well if you think its ATX, then the corsair unit should be fine. hoepfully prices will be good in canada.
July 22, 2010 4:47:39 AM

79.99$ for the same PSU!
July 22, 2010 6:37:46 PM

Thanks! AMD.com says that a radeon 4850 needs A 450W PSU.

tony, yeah they only give a guideline though. and based of full system drawe. the 400vx can supply more than enough for a 4850. and when you get your new gpu load will decrease, meaning better efficiency too.
July 22, 2010 11:46:34 PM

OK, Thanks for all the help!!!! greatly appreciated!

i was wondering is an AMD Phenom 9750 Quad 2.4 GHz core fast enough for medium to high end gaming? i heard that this processor is very slow compared to a AMD Athalon dual core 2.4 GHz, is this true??. Will the 4850 Bottleneck my CPU???
a b U Graphics card
July 23, 2010 2:51:24 AM

No that's not true. They are the same clock per clock, core per core. The Phenom has 2 additional cores. (assuming you are talking about an original Athlon x2 like the 7750). If you are talking about the Athlon 64 x2, then the phenom will be a touch better clock per clock, core per core. But I do not recommend either if you are buying new.

The Athlon IIx3 may lack L3 cache, but it make up for it in clockspeed. the 440 is 3.0GHz with 3 CPU cores. Currently, 3 cores is the most common limit to the number of cores most games can use. It will definitely outperform either of two previously mentioned processors and will beat the phenom in price by $15-25, at current market prices.

Phenoms are not great processors, but they are better than original athlons.

i woudl still suggest getting an athlon II, but medium level gaming should be possible with a phenom.
July 23, 2010 4:38:28 AM

Phenom 9750 Quad 2.4 GHz is my current CPU
a b U Graphics card
July 23, 2010 4:40:14 AM

yeah, that will be fine for most games.

if you want to play more modern games, or use max settings though, you will need an athlon II or phenom II
a b U Graphics card
July 23, 2010 4:04:23 PM

If that's your current CPU, keep it. For most games you will be fine. If you ever start having issues, you could always start looking into overclocking.

Get the radeon 4670 dude if u can't upgrade ur psu. It doesn't need external power supply. There is a 1 gb ddr3 version of 4670 HD and its cheap also.

So is the faster and DX11 5670
July 27, 2010 1:34:39 AM

Thanks, Ive already got the HD radeon 4850 it hardly fits in my case.... i had to remove something from a PCI slot and from a PCI-E X1 but it fits. I'm still waiting for the power supply hopefully its powerful enough for this card!!! THIS CARD IS HUGE 4 times the size of my 4650. i was thinking about getting a 4670 but its not powerful enough its not worth the money! It has half the memory bandwidth, half the memory bus type, half the shader processors, thanks for the suggestion but like i said I've already got the card.
