Dude....50euros for a board is okay.(Board and Processor together are cheaper than a comparable Intel)
And regarding the Power...You are talking shit.
I can play BF3 on High with good FPS and on Ultra with normal FPS, the only thing limiting is my graphics card(HD5770).Since he has a better one it OBVIOUSLY needs to be his processor which is limiting(Or his ram, since I have 6 gigs).So shut up if you cant think about the given facts.
Sorry but apparently you don't know shit, I dont even know the architecture of his i5, but fact is i5(2009 one, 2.6ghz) is on par with the phenom II and obliterates it when overclocked.
You can't compare FPS with someone just with knowing GPU and the processor, nothing else, its OC related, resolution(!) related, drivers related (!!) I could go on on this...
Ram (You need 1.5gb for BF3(1920x1080ish resolution) and 1gb for W7 and background) doesnt have to do anything with fps(DDR3 2133mhz ram and DDR3 1333mhz ram, difference in fps? practically NONE, it would only limit fps if he wouldnt have had enough ram, 4gb is way more than enough), another smart statement right there.
Also, why the fuck would anyone upgrade a 2009 rig with 2009 components, seriously, atleast if youre an AMDfail fanboy suggest him to wait for bullshitdozer series.
You tell me intel is expensive like hell, then in the same post you tell him to upgrade his 2009 rig with 2009 components, wat.
