Hi Everyone,
I have a 250 watt PSU (relatively fresh HP system). The integrated Intel Graphics is a piece of shit and I wanna upgrade to some good AMD ones available out there. One that power assassins creed 1,2,3, NFS Most Wanted 2012 and Ghost Recon AW 2 will do good. I specifically don't require ultra high graphics performance.

My question is can I get a good GPU for my setup? I've currently looked at some AMD Radeon HD 6450, 6570, 7750 etc...

My conf is basically the original Presario cq3320ix out-of-the-box with an additional 2gb ddr3. Since hp doesn't allow to use any PSU, i'll not wanna upgrade it. Unless, it's an absolute necessity.

Thanks

I would suggest getting a 350w psu at the last, because your system with a dedicated graphics card will draw some power, and will exceed your 250 watt psu. The card i think you'd like is a radeon 6670. It will run most modern games as well, so you won't have any problems with that ;)

Ya, I won't mind upgrading but I can't find a compatible one for my Compaq CQ3320IX. There is no much info available about the PSU, at least not to my knowledge. AFAIK, it's something custom-made HP PSU, proprietary model, like ones that come in dells

Thanks for your 6670 suggestion, it's a good card!

That PSU can't handle an external GPU, most probably won't even boot. You'll have to get a better PSU and for performance/price ratio, anything less than a 7750 is a waste of money.

However, with such an old system I'd recommend a full upgrade, since next gen games (PS4/Xbox one) will require a better processor and won't run even if your graphics card is good enough.

I also found an older thread with almost exactly your computer and question, it should help you make a decision.

You have a standard ATX case so you can use any standard ATX power supply.

Dell has not used proprietary sized power supplies in years either.

350 watts is about the lowest wattage quality models you can find. Antec makes a few. The Corsair CX 430 is also a good option as it's decent quality and often under $30.

Here is a list of power requirements for systems with pretty much any card. Overclocking headroom is included in these recommendations.

Stick with Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ and Antec for quality.

Here is a good article Tom's does every month listing the best graphics cards for the money.

That's exactly identical to my bulid (except for my overclock, I hate overclocking)
Very well then, i'll replace my PSU... but still now I can't find a compatible PSU for my system??
Any recommendations??

PS: 7750 requires only 75 watt (since it has no auxiliary power conductor, so PCI-e can only supply 75 watt max,right?), and my Pentium DC is rated at 65 watt (max), and I have only an Samsung IDE 7200 rpm HDD. Guessing it might run!!

Because you're actually using a pre-built system from your computer manufacturer, it would make sense that it is a proprietary PSU. What i would do is this:
1. I believe your motherboard ISN'T proprietary (It seems to be made by foxconn, and it might be a standard microatx motherboard. If that is the case (No pun intended here), then buy a new case for your computer. Then you'll be free to upgrade as you wish. A decent gaming case will only set you back $40 - $50, and a good PSU will only cost about $50 - $60 (For the wattage you want)

2. Your processor seems to be one on the socket 775. That also happens to be the socket that the Intel Core 2 Duo/Quad processors use. If you want to play games at good fps, you can upgrade to a Core 2 Quad/Duo processor for $100 - $200.

3. Get more ram! 3 GB of DDR3 isn't much for playing games like that. 4 GB would be the minimum. Replace all the ram you have, as dual channel memory works best.

If you do all this, you should have a small compact gaming system for about $300 upgrade. Remember, this is ASSUMING your motherboard will be compatible. Check the motherboard to see if it is compatible with standard ATX/uATX cases, because then that opens a new world of possibilities for your "gaming" rig.

yap, that's exactly as you said... I have no luck than upgrading the whole thing...
But, here's the bottleneck, I'm in India. For me, $300 = something around ₨ 16000+ and that's way too much currently. And prices here are subject to custom duties so a cost of $300 @ 100% tax = $600 = ₨ 32000 (my whole monthly income) :(

Perhaps i should have said this - Your case may support custom motherboards. If it does, just buy an AMD motherboard and AMD A8 5600k APU ($100 on Newegg). Then if you use a radeon 6670 you'll get much better performance than either alone (Because APUs have built in graphics that are very good, so if you use a 6670 or a 7790 with an A8 or A10 APU, then you will be able to run "Hybrid" crossfire. )

Remember, if you get a new motherboard, CHECK THE SOCKET! If you want the latest and greatest AMD APUs (Trinity) you will need to have a Socket FM2 motherboard, which is about $50.

I've put together a small PCPartPicker list for you. This is what you might want!

*NOTE: THIS IS NOT THE PARTS WITH PRICES IN INDIAN RUPEES, THIS IS JUST A LIST OF PARTS YOU MIGHT WANT TO USE*

PCPartPicker part list / Price breakdown by merchant / Benchmarks

CPU: AMD A6-3650 2.6GHz Quad-Core Processor ($69.99 @ Newegg)
Motherboard: MSI A55M-P33 Micro ATX FM1 Motherboard ($47.99 @ Newegg)
Memory: Corsair 4GB (2 x 2GB) DDR3-1333 Memory ($34.98 @ NCIX US)
Video Card: Diamond Radeon HD 6670 2GB Video Card ($65.00 @ Amazon)
Power Supply: Thermaltake TR2 430W ATX12V Power Supply ($22.00 @ Newegg)
Total: $249.96
(Prices include shipping, taxes, and discounts when available.)
(Generated by PCPartPicker 2013-05-29 04:30 EDT-0400)


Remember,
Your case has a uATX board installed already. This should fit inside. Find parts similar to this if not the same, but try and keep the brands the same. For your power supply, use Seasonic, Corsair, Thermaitake. Those are brands that I know are very reliable, especially in the hot dry conditions of India.

It may run, but you'd be pushing the limits and chances are the computer will be unstable, probably get some bluescreens until the PSU dies and then you can only hope that it didn't take the motherboard with it.

if you can't fit a new ATX PSU in there, your best cheap bet would be one of those cheap cases that comes with a 400-500 PSU. like the ones in this list http://www.coolermaster-usa.com/category.php?category_by=0&category_id=1625&category_name=Enclosure%20+%20PSU

Good suggestion, for my new system, AMD A8s costs something around Rs 4000-500 (<$100) probably i'll set up a new gaming tower. Now currently zeroed on a GIGABYTE board some Corsair 8 GB + 4 GB + Transcend Info 2 GB. That MoBo supports Corssfire so a 6670 or 7750 will rock! And I've got hold of a Corsair 500 watt PSU at a price less than what I expected. Thanks man. My new setup costs something around 15000 (<$300).

Seriously thinking .... I was mad to get this dummy Compaq with shitty money monster intel!!.



It's hot and humid (not dry ;) ) to increase the effect!
Don't ever attempt to power on your computer during mid-day... Forget gaming, probably you will get BSOD or forced reboots due to over heating after 5 minutes. And this also means that I have to get a liquid cooling system for my cpu.

I got a Corsair 500 watt, unfottunately it's incompatible... that's why I guessed so... Hoping that you are right, I may have to call my hardware junkie friends for accessment on my PSU

a new case will only run you $40 (Which i believe is around 2000 rupees or something (50 RP to $1 correct?) so it shouldn't be too expensive)
A new case will let you install your PSU, a new motherboard, and basically let you build a new system without breaking the bank. Building a whole system brand new will only cost you $400 (The one i suggested) so you may want to go with that.
