[ i5 2500k & GTX 560 Ti 448 ] vs. [ i3 2100 & HD7870 ] - Page 3

post #21 of 37
If I had to choose I'd take the 2500K and 560 448, especially since you play BF3 online.

The 560ti 448 isn't at all a 560 class GPU either, it's got a lot more punch than I think a lot of people realize. Just a percentage or two slower than a 570 and 1.3GB of vram instead of 1GB.

Actually I was looking at an even better PSU, which fits the budget with 2500k and Gainward 560 ti 448: Corsair TX650 V2 @ 69,90€
I have 6 old SATA HDDs which I will transfer to the rig also, so need an extra beefy PSU. I've read that on startup a normal 3.5" SATA drive draws 33W.. and calculate that x 6 ( = ~200W) tongue.gif

"Besides, no one abolished the problem of high start-up power consumption – for example, the plain Barracuda 7200.8 may draw up to 2.5A from the +12 V line at start-up. Add 3 W drawn from +5 V to get the peak start-up power consumption of 33 W! What if there are two or three such drives in a system? In this case you should play safe and take a PSU at least by 100-150 W more powerful than processor+video+motherboard require. Food for thought."

If your going to RAID 0 or 1 all of those drives, I'd worry about it a bit more but if your just going to have a drive or two bootable I wouldn't. They don't take much when idling.
Anyway you cut it a TX650 will supply that system well. If you ever wanted to SLi those 448's, then you'd want to step it up to 750 or 850.

One other thing. Will DDR1333 memory restrict overclocking, or do I have to have DDR1600?

Also, I see DDR3 memory with both 1.65V and 1.5V. Does it matter which one I choose? (Z77 + i5 2500k for those that haven't read from the beginning)

Nope. What memory do you have in mind?

I would say the i3 and 7870 for power consumption and the fact that you won't see any real difference between the 2500k and 560. At load, the 7870 will consume 50-75 watts less, and obviously the i3 will consume less than the i5. In the long run it'll cost less.

This kit is on my list:
TeamGroup Elite 8GB KIT DDR3-1333 PC3-10667U CL9 2x4GB (30,90 €)

Going for any 8GB DDR1600 kit will cost over 40 € .. So I'll have to change the PSU then to a "weaker" one.

This made me go with the i5 2500k: http://hardforum.com/showthread.php?t=1654043
I had blindly looked at the scripted SP benchmarks, where all the CPUs perform within ~5% range. But in multiplayer it's a whole different ball game.

I think you'll be happy with it. You'll have very close to the same performance as my rig.
