$600 december build, - radeon, + gtx560 ti.. psu?

[dhart1980]

so here's my question, assuming all the components will be exactly the same as the $600 marathon build ( http://www.tomshardware.com/review [...] ,3097.html ) for dec 2011 except for the PSU which would be a:

Corsair CX430 V2 Power Supply (CMPSU-430CXV2)
Voltage............................+3.3V.......+5V.....+12V........-12V.......+5Vsb
Max. Current....................20A..........20A.......28A.........0.8A..........3A
Max Combined Wattage...120W..................336W.......9.6W.......15W

because i already have it, would that be sufficient wattage to swap the radeon out for a Geforce GTX 560 Ti?

Thermal and Power Specs:
Maximum GPU Temperature (in C) 99 C
Graphics Card Power (W) 170 W
Minimum Recommended System Power (W) 500 W
Supplementary Power Connectors Two 6-pin

I noted on the power consumption benches that it never goes above like 310 watts, but i'm not sure if that means what i think it means, because it had the "at the source" modifier.

bottom line is, i would like to skip a PSU purchase if at all possible, but i also don't want my pc to catch on fire once it's done..

i've tried several psu calcs but even with the stock build they suggest a 700 watt psu which seems seriously overkill.

In my opinion cx430 should run the card but it will be stressed to 100% under full load.So you would need to upgrade your psu sooner or later.

making me think i should just go the stock 6870, especially now that amazon has it up for $164 with free shipping...

starting to think the 560 ti would be nice, but then i thought about how skyrim etc would probably run fine on mid settings on the 6870, saw the price point..

thought about how online games aren't THAT intensive... i dunno.. i think i might be suffering from wanting the best card for the cash out there, i always talk myself off that ledge...

also with this new $164 price point, it puts the radeon in pretty good contention for best per $, BUT... i sure do hate radeon. LOL

their drivers are so horrible most of the time... i still have nightmares about when secondary displays got popular and i went ati...

(also a $20 mail in rebate if i'm not feeling lazy... 144 bucks?! that's a crazy good price.. almost $100 less than the 560 ti... yeah obv the ti has much better performance, but per $... not so sure anymore)

Drivers aren't an issue for radeons anymore,at lest for single gpu systems.
