Do I need a new processor?

I'm new here and was wondering about whether I need a new CPU. I'm not too good with computers so bear with me.

I have an Intel Core 2 CPU, 6420. For my graphics card, I have an Nvidia GeForce GTX 560. I know my graphics card is new and high powered, and what I want to find out is whether my Core is bad and/or old, and if I should upgrade, where should I go? I was thinking an Intel i5 750/760, but should I go i7? Or even i3? I am using Windows XP if that is relevant.

I want to know this because, just a couple weeks ago I had an ATI Radeon 2300/2500, and now I can run games better, and at higher graphics settings. However, if I run too high, and even minimum on more recent games (Civilization 5, the Witcher, even Civ 4) it seems unstable, and can crash at times. So, would it be a good idea to spend 200-250 bucks for an i5 processor?

The fact that your computer seems to be unstable leads me to believe your power supply (PSU) is too weak to power your entire system.

The GTX 560 alone has been measured to use 160w of power under typical gaming conditions.

The Radeon HD 2300/2500 uses less power than the HD 2600 Pro which has been measured to use about 31w under typical gaming conditions.

The question is what PSU do you have? I would say you need at least a 500w good quality PSU for your system. You need to open the case an take a look at the sticker and provide information similar to the below...



Brand Name: Seasonic
Model: SS-700HM (700w PSU)
Amps on the +12v rails: 18a each on the 4 +12v rails
Total Maximum Amp: 56a

Total Maximum Watts on +12v rails: This information is not provided, but is easily calculated by multiplying 56a x 12v = 672w

I have my computer plugged in through a power strip, which also uses the printer, monitor, and speakers, so would that be detrimental?

Anyways, I think that an Intel Core i5-2500k would be better than the 760, and only for $10 more. It apparently requires LGA 1155, which I don't know if my motherboard has. So, basically I have to open up my computer?

No issues unless the outlet has problems providing consistent power.

You need a new socket 1155 motherboard for the i5-2500k, it cannot be installed in your current motherboard.

You need to open your PC and provide similar information as posted above. Post a picture of the sticker if possible. But more than likely you need to buy a new PSU. I recommend the following XFX 550w PSU for $50 after rebate. It is manufactured by Seasonic who are known for manufacturing very high quality PSUs.

Yikes. It turns out my PSU is a 6 buck piece-o-junk.
I believe this - http://www.google.com/products/catalog?hl=en&q=ps-5301-... - is it.


So, being 300 watt, I should get an upgrade to 500? Is the PSU you suggested compatible? And does this mean I don't need a new processor?

Also, how much of a difference is there between a 300 watt and 500 watt in terms of performance? Is it an upgrade I should do ASAP, or could it wait for a new PC this autumn?

make sure to get a branded power supply,

if you get that core i5 2500 then you will also need to buy more ram

make sure you only buy ddr3 ram and a socket 1155 motherboard to use the cpu in

id recomend getting a 700+ watt power supply becasue there just so cheap now adays anyway and its better to have too much power than too little plus i dont want to have to bother with working about power draw

A $6 psu!!! Still being sold!!

Replace it asap.

The 550w XFX should be good regardless.
It will probably cure your instability issues.
Also, make certain that your graphics drivers are up to date.

If you have performance problems that bother you, the cause will be the cpu. It is 5 years old, and obsolete by today's standards.

To replace it, you are looking at $125 for a i3-2100, $80 for a H67 motherboard, $40 for 4gb of DDR3 ram.
You could spend more, but that would be a major improvement.

Alright, I have a motherboard, CPU, and RAM possibility, in addition to the PSU suggested:
Mobo: http://www.amazon.com/P8P67-REV-3-0-Supported-Motherboa...
RAM: http://www.amazon.com/Corsair-1333MHz-PC3-10666-240-pin...
CPU: http://www.amazon.com/Intel-i5-2500K-Processor-3-3GHz-L...

From what I can tell, this would be a good setup. Any feedback would be appreciated. These three and the PSU would set me back about 440 dollars, so, anyone know a bank that has lax security?.....

Joking aside, if I want to spent <$200, what would be a priority to get?

That is a good cpu/mobo/ram package that will last a long time.
If you wanted a good upgrade for less, look at the i3-2100:
http://www.tomshardware.com/reviews/best-gaming-cpu-cor...

It looks like that ram is a single 4gb module. That is really OK, but a 2 x 2gb kit would cost the same and give you dual channel operation.

But, I would replace that psu IMMEDIATELY.
June 26, 2011 10:05:19 PM

Well, that would shave $80 off the cost, for 360 dollars. More reasonable, I guess. Now, is the RAM really important for me to get? I have 3.37gb of RAM, do I really need more? Also, I don't know what overclocking means, so if I don't plan on doing that, would the i3 2100 serve me fine? And is it really that much of a step up from the Intel Core 2?

For now just get the PSU I recommended. Save up some money for a good upgrade so that you can buy a Core i5-2500 or i5-2500k (if you are going to overclock) and a good motherboard (H67 chipset or P67 if you are going to overclock).

The Core i3 is a good upgrade from your C2D E6420, however, if you are patient then you can upgrade to something even better with an i5. Your E6420 will bottleneck the GTX 560 a little bit, but it won't be bad at all. Saving up money for an i5 will save you money in the long run over an i3 because of the higher performance level. That is partially due to the fact that the i5 is a quad core CPU. Many games can take advantage of 3 cores right now. The are a few games that can use 4 cores and more are likely to come.

Regarding RAM, it seems you currently have a 32-bit operating system. That will limit you to around 3.25GB of RAM regardless of how much more physical RAM you install.

If you are still using Windows XP, then it is recommended you upgrade to Windows 7 64-bit which will allow recognize more RAM when you upgrade your motherboard. There may not be any Win XP drivers for the motherboard you will end up buying.
June 26, 2011 11:19:47 PM

Yeah, I was thinking about upgrading to Windows 7, but a lot of the games I play are apparently incompatible with it, especially 64 bit. It seems that you can run things in Windows XP compatibility mode, but I found that games like Fable TLC, Black and White 2, and KotOR I/II are supposedly incompatible with Windows 7. I think I'll just get the PSU, $50 isn't too much. Thanks for the advice, I came into this topic completely lost with CPU/PSU/RAM/etc etc.
