I am looking to custom build a PC, mainly for gaming. I would like to know if the below hardware is a good choice for the price which is £474:
CPU - Intel i5 750 (2.6 GHz, 8Mb)
Memory - 2GB (DDR3 1333)
MoBo - Asrock P55M Pro X-fire DDR3 2133 x4 P55 chipset
Graphics - ATI 4850 1Gb (PCI Express)
Thanks for any suggestions.

Can you follow the sticky post instructions? We can't do alot with this information.
October 20, 2009 9:19:20 PM

Sorry,I just used the form on the front page to post this question and they didn't show any rules/guides there for the question.

APPROXIMATE PURCHASE DATE: the closer the better, a couple of weeks
BUDGET RANGE: No more than £500

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming is the main reason for this build

PARTS NOT REQUIRED: keyboard, mouse, monitor, speakers, OS

PREFERRED WEBSITE(S) FOR PARTS: Open to any suggestions. Mainly looking at though for the moment.


PARTS PREFERENCES: As its gaming the Graphics card is an important factor. The parts that I am a bit confused on are do I actally need a 4 core processor (i.e. the i5) or would a Core Duo suffice? Also, I know next to nothing about MoBo choices.

OVERCLOCKING: Possibly, but I wouldn't do it myself. If the company offered it I might go for it.

SLI OR CROSSFIRE: Possibly if the price is right

MONITOR RESOLUTION: Any, not really relevent.

ADDITIONAL COMMENTS: Any suggestions on recommended companies would be welcomed as well. I have looked around as much as possible, but any advise is much appriciated.

The monitor resolution is absolutely critical or we have no idea how powerful of a GPU you need.

+1 on the resolution being relevant.

Good UK online retailers in my experience are,,,, At the very least they are good for choice.

Oh right, I didn't know it was that important. Well the monitor is a 19" TFT (at the moment) and it would be good to run the games at 1280x1024 but if the cards are too expensive for that, 1024x768 would be fine.

I guess the main question I have is do I need a quad core (i.e. i5) or can I go for a cheaper Core Duo and then spend the extra money on a more expensive graphics card.

I think 4850 is enough for 1280x1024, or if you want DirectX11, you can go 5750 or 5770. I would stick with I5, its not that expensive, and will be a good basis for further upgrades, if decide on them at a later time.

About multi GPU, the first echelon of boards are Asus P55 PRO, MSI GD65 and Gigabyte ud4(P) (there are just a few Evga/Asrock boards where I live so I have no xp with them). For single GPU, any board at price point below the above boards, which has all the connectors/slots you might need.

Two more points. I would get 4GB of RAM, and a better HDD (like WD640 black or Samsung F3) since they tend to fill up really quick with today's games.

At that budget an i5 might be too much. For a straight gaming machine, a dual core AMD AthonII/AM3 with a stronger graphics card like a 5770 would perform better.

I only know US pricing but here is a parts list with some newegg links so you can see some specs.

Athlon II x2 Regor 240, 245 or 250


4GB (2x2GB) Gskill DDR3-1333 RAM (cas 8 timing, 7 is better, 9 is worse)

SAMSUNG Spinpoint F3 HD502HJ 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive

ATI Radeon HD 5770 GPU

I think thats all you had listed above. Those components will run a nice HD LCD at 1920x1080 on the latest games at high (maybe not ultra high) graphics settings.

A quality power supply and a case with good airflow are also necessary for the reliability and longevity of your system. Let me know if you want some examples of those.

Hey. Thanks for your reply, but I think you have the currency conversion mixed up. All that comes to $437 which is about £260, about half what I was going to spend. (Obviously I have to have some for a case and cooling)
However, somthing interesting you said: you think it's worth spending less money on a CPU and more on a GPU?

Low resolutions like yours actually put more stress on the CPU than higher resolutions. I would stick with the i5 build. I would bump it up to 4GB, though.
October 22, 2009 9:27:35 PM

Ok so sticking with the i5 build, how about these:

Intel Core i5-750 Quad Core 2.66GHz 8MB Processor (£150)

Corsair Memory Corsair 4GB 1333MHz DDR3 CL9 (£72)

Asus AM3 AMD 785G DDR3 mATX A L (£70)

Western Digital Caviar Blue 160GB 3.5" SATA-300 8MB (£30)

Sapphire Technology ATI Radeon 5770 HD 850Mhz 1GB PCI-Express HDMI (£131)


Which means £50 for the case, PSU and cooling, which should be more than enough.

I don't really know much about MoBos so any guidance there would be great, however I don't really want to spend more than £80 on that.

Also, I am not limited to any distributor, so any further suggestions there are welcome.

You need to get a p55 socket 1156 motherboard to go with an i5 CPU.
Something like and ASUS P7P55D.

Case, cooling and particularly PSU should not be skimped on afterthoughts. Poor power will make for a computer with flakey problems, lockups, etc. A bad power supply can even damage the rest of your PC. Any decent power supply is going to cost you 50. Like this Corsair 450W.

You want to look for a case with lots of fans to keep everything cool. A cooler system will make your components last longer and operate more stable.

The coolermaster Hyper 212 is a good, inexpensive cooler that will work on any CPU socket.

The problem is we are now getting above your budget, which is what I figured would happen. Its very hard to make a decent i5 gaming system with less than $800 US. Going back to an AM3 motherboard and a Phenom II x3 720 might be necessary.

I would agree with the motherboard and HDD shortstuff posted. (but he missed that you had an i5 CPU in the same build :ouch:  )

In general, having a fast dual core CPU and a strong GPU gives better gaming performance than a slower quad core and a weak GPU. Most games are more GPU intensive than CPU intensive. With a 5770 you will be able to replace your monitor with a nice 22-28 inch 1380x1050 to 1920x1080 LCD and still be able to play well. Its a good choice if you plan to keep it 3+ years.
October 23, 2009 9:20:19 PM

Ok, fair enough. Having looked at the prices of the things I thought of as negligable, that CPU does seem a better option. (I never knew there which things as triple cores).

So rounding up all the suggestions in to one, how about this configuration:

AMD Phenom II X3 720 Black Edition (2.8 GHz) (£92)

Gigabyte AM3 AMD 770 DDR3 A GL (£70)

Western Digital Caviar SE16 320GB S300 16MB (£33)

Corsair Memory Corsair 4GB 1333MHz DDR3 CL9 (£72)

Sapphire Technology ATI Radeon 5770 HD 850Mhz 1GB PCI-Express HDMI (£131)

CoolerMaster Hyper 212 Plus Cooler (£20)

Corsair Memory 450W ATX PS/2 SATA 12V (£50)

CoolerMaster Elite 330 Black Midi Case + Window (No PSU) (£37)

Coming to £505, but I will shop around a bit anyway.

The have 2 questions now I suppose:
Is a 450W PSU powerful enough for the graphics card and CPU?
No one has said much about the memory. I know this is a bottle neck for computers and is therefore a very important factor. Is there any suggestions on what to look out for in the specs for memory?

Thanks for all your help.

RE Memory: CL7 is going to give you a small performance increase over CL9 and better overclocking options. You might see if Gskills Ripjaws CL8s are the same price as Corsairs CL9s.

RE: Power, yes that corsair 450 is will be great paired with a single 5770.

Yes 450W should be enough. And you don't need a CPU Cooler if you aren't going to be overclocking the component yourself.
November 3, 2009 1:49:47 AM

I don't know if it's too late, but If you go with a 600W PSU, you will be able to crossfire.
Next year the same GPU will be much less expensive and will greatly help you,especially if you're going to have a 1920x1080 screen.

Just a thought.... that I didn't have 2 years ago... and now I've got a PSU doing nothing..... ;)
