Hi there

I'm pretty much a novice at upgrading and knowing what component will fit in which slot. I have recently installed GTA5 and Witcher and although it runs ok with the lowest gfx settings i would like it to run a lot better. I know i'll need a better PSU and a better GFX Card. I am wondering based on the below spec what your advice would be? Is there anything else that needs upgrading and what components do you suggest. I was looking at around £80 for a PSU and anywhere upto £150 on a GFX Card 

*Lenovo H420
*O/S- Windows 7 64 bits
*Pentium Dual Core G630 @ 2.70 Ghz
*6 GB - DDR3 PC3-12800, DDR3 PC3-10600
*Nvidia GeForce GT 520
Current PSU is 280w

For PSU i was looking at

or

http://www.ebuyer.com/429987-corsair-cxm-750w-semi-modu...

Would they fit in?

Then gfx cards maybe

or 
http://www.ebuyer.com/621487-evga-gtx-750-ti-ftw-acx-2g...

Or am i completely off target. Would any of these even fit into my current system? would i need to upgrade the CPU? If so how? lol.

Thanks in advance for any help you lot can give.

That is a fairly low-end system for The Witcher 3 and GTA5.  For a graphics card, I suggest spending a little more for something like the EVGA GTX 960 SuperSC.  If you can afford it, the Zotac GTX 970 4GB would be better.  Either of those power supplies will work with these cards.  Your CPU could also use an upgrade.  Here is a post at Lenovo regarding which CPU's are compatible, unfortunately, the highest end CPU it will take is an i3.  Because this is a pre-built system, your motherboard will only take a limited set of processors.

Yeah i did figure it would possibly be a CPU upgrade also. At that stage if i have to get a new CPU, GFX Card, PSU and possibly a few gb of RAM maybe it would probably be easier to buy a new system? 

Looking at his post he did replace his CPU with 

Intel Core i5 2500K 3.3 GHz Quad-Core (CM8062300833803) Processor

Would this work on my system?

 

Or would it have to be the intel i3-2120 - http://www.amazon.co.uk/Intel-Sandybridge-Dual-Core-Processor-Warranty/dp/B004KZDV8E 

 

If i didnt upgrade my CPU and just did PSU and GFX Card would it still work or do you think it would really be important to upgrade the CPU?

 

Cheers for the help

If the poster on that Lenovo forum was able to get it to work, you may want to try it.  However, as the poster also pointed out, Lenovo doesn't support CPU upgrades, so you can try it at your own risk.  The reason why upgrading CPU's on pre-built PC's is risky is due to most PC manufacturers not using standard off-the-shelf motherboards making CPU compatibility more difficult to determine.  Some motherboards will take all processors for a given socket, others may only take certain processors for a given socket.  Off-the-shelf motherboards publish comprehensive lists of compatible CPU's.

 

Both The Witcher 3 and GTA 5 are recent games designed for multi-core CPU's, a quad core processor could be beneficial.  If you aren't sure, you can upgrade your GPU and PSU, see what the performance is, then determine if you need a new CPU or not.  Here is an article at Eurogamer about CPU's and The Witcher 3.

Thank you for the help and advice. My brother in law was able to help me with a 650w PSU that he had spare.

I bought another 4gb stick of RAM to take it from 6 to 8 (removed the 2gb stick)

I bought an Intel i5 2500k 3.3ghz cpu and this is working brilliantly 

and finally i followed your advice and bought a EVGA GTX 960 SuperSC. In total the upgrade cost around £220 but i am more than happy with the performance now. 

 

I suppose the next logical steps really would be new motherboard and new case, i'll save that for Xmas :)

 

Thanks again for the advice and help
