You should first upgrade your graphics card on your tight budget since it'll benefit you most. For your budget and power supply envelope I'd go with the radeon 4770 or 8800 gts/9800 gts. They require a molex power adapter. Does your power supply have a molex adapter? You can google it to see an image.
Whats your budget? If you could upgrade your motherboard and processor you'd be getting more value than buying a dated cpu. Spending about $120 which includes the gpu's I suggested would be better than buying a overpriced dated processor. You would also be able to upgrade to better parts later on. Still the graphics card alone will probably make your system 3X better.
9800/8800 or 4770 have enough value to upgrade to them since they're so cheap. Heck they perform better than entry level cards like 5670/6670 which cost about $100. As long as you don't expect to play battlefield 3 at max graphics those second hand cards are worth it.
Neither your video card or processor are good enough for modern games, but your going to see a much larger increase in gaming performance from a better video card right now than CPU.
9800 and 4770 can play games at 720p modern games. Considering that he's been going along with a horrible price/performance card even when it was released these cards will be amazing. They still are bandaids if he has a bunch of recent and future releases he want to play.
So..I have a molex power thing. Is a 4770 a big boost? And just want to know which is better? My budget is 56$
And can I even run that proccessor? I dont want a whole new system. Cant afford since Im only 15..
i had a 4600x2 and upgraded to a 6000x2 there was a noticable increase in performance. if you can get a 500w psu and add a 98gt or gts 250 and you will have a well balanced entry level gaming pc.
that will in most cases allow 1080p medium on dx10 and low on dx11(though the card will only run em in dx10 max) games.
als you will want ddr 2 800 minimum of 2 gigs.
thing is your gfx is seriously poor by any standard so while i saw a major improvement as my 8800gt was bottlenecking by about 7% on the 4600 so when i upgraded the cpu it freed up the gfx 2 so it became more noticeable. your gfx is much weaker so the change many not be so pronounced.
the 6000x2 is pretty expensive for what it is so if you could save another 100-150 over a few months you would be able to jump platform to the i3 series which will give even more.
So a video card would be a better improvement then processor?
If so can you recommend me a card for 50$ Thats on newegg.
New graphics cards are not worth it till you spend about $100. These on AMD side they are the HD X770/X750/X790 or above, Nvidia is the X50 or above. Below that your get horrible performance per dollar. For $50 bucks ebay has cards that perform as good as these $100 dollar cards but for half the prices. That is why I suggested ebay even though they have they may not have warranties. Usually this doesn't matter since hardware that isn't abused will outlive their users satisfaction with them.
