New Video Card

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.

4850 is the most powerful card you've listed so far. What power supply do are you using?

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.

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.

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.

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.

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!

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?

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???

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.

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.

79.99$ for the same PSU!

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

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

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.

Phenom 9750 Quad 2.4 GHz is my current CPU

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.

So is the faster and DX11 5670
