Now the other questions would be;
What sort of games are you going to play? (name some games)
What level of detail are you willing to accept? (low, medium)
How much bigger can you make your budget?
For £200 you could possibly get second hand parts on ebay and scrape together a very budget PC that would play casual and some older games. Using an AMD APU you'd save money and have a graphics card and CPU in one. An A4 would probably be your only option on that budget, though, which would run stuff from 5 years ago but very little in the way of modern games.
You can build a gaming PC that will play most games on low to medium at 30fps for £400 using an A8 AMD chip and 8GB RAM. For another £100 more you could get a 7750 2GB graphics card which will play pretty much everything in medium with that CPU as well.
hello i would like to ask all you people what the best part are for a desk top if i am willing to make my own gaming pc i would like to make it within a price range of round £200 if u could get back to me and let me no i would be very greatful thank
Welcome killler4321 ...
Now that's quite a problem as a 'gaming pc' hand built by your good self will cost a lot more than your 'budget' ... let's add an extra £400 and then you might be just 'playing with soldiers' ;¬)
