Hello,
I am building a gaming PC using Asus Radeon HD6850 1GB on a budget.
I plan to game at 1680x1050 with med-high details. The games include GTA IV, BF:BC2, Metro 2033 etc.
For cpu, I am looking at Athlon II X3 445 or Athlon II X4 635 or Core i3 530 but prefer X3 due to lower cost.
Will the X3 be a bottleneck for the HD6850?
Is a higher end cpu needed?

I would love to get core i5 or new Sandy Bridge line but its too expensive atm. I am not interested in video encoding/decoding. Is the extra cost worth the benefits?
(Am in India - so the cost goes up from 8K for Athlon II X3 + ASUS mobo to 15K for core i5 + Intel mobo)

TIA

You'll be just fine at that resolution with any of those processors. Yes, the X4 can push the card just a bit more, and the i3 530 about the same amount more, but you will not notice it at that resolution. Heck, you won't notice the difference between the 3 of them at any resolution, honestly. Go with the X3. As for an i5 or SB, for gaming, you're not really going to notice that much of a difference. Yes, you may get higher framerates, but (again...at that resolution) you're not going to be anywhere close to needing to worry about framerates dropping low enough to cause even the slightest bit of hesitation/stuttering in any of those games. Metro is demanding, and GTAIV is a POS console port that runs like crap on 90% of PCs, but you should be just fine regardless of which of those 3 procs you choose.

Thanks for all your replies.

@GeekApproved - I dont care much for non-gaming applications (firefox or office take very little processing power). Any specific reason for avoiding Athlon II?
By i3, did you mean the new SB or the current available? I read in some of the reviews that the extra core of X3 will be useful for games like GTA IV. Does the i3 make a significant impact?

@jj463rd - That was my initial plan but my cpu went kaput last week and I am without a pc right now :(
Intel has not announced any plans for releasing SB in india and i heard rumors that they wont be coming before Q2 2011.

Just read http://www.tomshardware.com/reviews/gaming-processor-core-i3-athlon-ii,2666.html
and again Core i3 seems good buy - I am very confused here

You mentioned Phenom II in the post title. The black edition Phenom II's, both x2 and x4, with C3 stepping, are all excellent gaming cpu's. x2 555 and x4 955 would be my recommendations.

Went through a lot of sites and reviews and i3 seems to the best option right now - it is consistently beating the athlon X3 by more than 5 fps in most benchmarks.
I have decided to go for it.
Thanks for all your help :)
