I'm really new to building and upgrading computers so bear with me.
I am looking to upgrade my current build to improve it's performance while gaming. From the parts I have currently, can you tell me what is letting my computer down in terms of performance and how I can improve it. I'm in the UK and using scan.co.uk as the website for purchasing items.
Graphics Card: XFX HD Radeon 6870
CPU: i5-2500K Stock Cooled
RAM: Corsair Memory Vengeance Blue 8GB
PSU: Antec Truepower 650w (The item is discontinued and could not be found on scan.co.uk so I just linked newegg)
Motherboard: Gigabyte Z68A-D3H-B3
From what I can gather, I think my GPU is letting me down the most and think it needs to be improved (once again correct me if i'm wrong). Is it a good idea to buy two graphics cards for my build or stick to one, and does having two graphics card have any major benefits or limitations apart from space inside the case. What graphics card should I go for ( I don't really have a preference in terms of NVIDIA or AMD cards).
Also, is it worth overclocking my i5-2500k at the moment or will it not really benefit me? Can my current setup support overclocking or am I going to run into problems. I understand I would need to improve my CPU cooling and would probably get a Coolermaster Hyper 212 EVO if I were to OC. If this wouldn't really improve anything im fine just leaving it at 3.3GHz
In terms of budget for the GPU, im looking at around £200 but I can deal with going over budget slightly.
Thanks for any help and sorry for the wall of text.
Your processor will be fine for current and new games for quite a while.
You could try to get a 660Ti or if that ends up too over budget you could snag a 7870.
In terms of power of the 660ti how much better is the 3GB than the 2GB card. The 3GB card is 60pound over my budget so I cant really afford it but is it a huge improvement. This may be obvious to you but if you look at this (http://www.scan.co.uk/search.aspx?q=660ti) what are the difference between some of the cards
