Hi guys, Need your advice, i am bit stuck on what to do.

and let me start of thanking ALL of you in advance i really do mean it, my other queries were also answered really well :D 

So back to the topic, i just AFTER 4-5yrs of using my old i5 decided to change my pc, cause it was not really performing anymore.

So i in a VERY tight budget decided to get the AMD 8320 & Gigabyte 970a Ds3p Mobo. Cause i really felt price/performance it seemed like a good buy.

Now i am using a corsair cx600 on a Sapphire HD5770 which let me say is absolutely hopeless to play new games.

Have decided to go for a new Card, the Zotac gtx 760 AMp edition which i know my power supply will support
OR
for the R9 280x now the problem is xfx is giving life time warranty which makes it an amazing buy and i do love the ASUS/MSI cards also.

So would my PSU support ? cause xfx is asking for minimum 700W Same as sapphire r9 280x.

Im in india so the gtx 760 comes up for 350$ and the r9 280x comes for approx 430$. i kow the r9 beats the 760 but pls tell me what to do im so losT :( ((

please do not change your cpu if still working, try do some overclock on it. you only spend money if you try to change your cpu right now. your i5 is fine for todays needs. The radeon 280x uses 1x8pin and 1x6pin conectors 75w from the slot more 75w from 1x6pin and 150w for the 8pin its about 300w maximum power. but if want OVERCLOCK you will get more powerdraw than the original clocks. try find de cheap 760 or 670 have the same power. you can run all the games in maximum configs 1920x1080. i wish to you good luck

Hey thanks for the reply :)  the issue is my i5 motherboard is the 1st gen MSI P55 GD65, which died 2 weeks back now i cant find any in stock and the ones which are available are really bad 1s. And i just thought upgrading it would be a better idea.

I bought a amd 8320 and a compatible mobo like stated earlier , but my main issue was that would my power supply CORSAIR cx600 support the r9 ? cause on their sites on XFX and sapphire its clearly written they need 700W power supply.

Also i know r9 280x beats the 760 but is it worth going for the r9 or 760 ( getting 760 for a really good price).

Actually if you look at most charts, depending on which i5 that is, you would be DOWNgrading your performance by going AMD. That said, you will bottleneck for the R9 simply because the R9 demands are only on par equal to the performance of a i7. I would go 670 or 760 as well as AMDLova suggested. I believe your only real problem your having is the 5770, but also depends on how much performance your expecting, what settings levels, what games we are talking and what FPS / setup your expecting to work in (i.e. triple 24" 240Hz displays all at 1900x1080 clocking 120FPS in BF4 set on Ultra 8xAA/AF???).

Hey toms thanks for the reply , im sorry i forgot to mention but its a 1st gen i5 760, and i was under the impression that amd 8320 are really good processors so how would it bottle neck r9 series ?

And ya in cs go even right now with my config
Amd 8320
Gigabyte 970a ds3p
kingston 4gb 1600
Ati HD 5770
and ya in CS.GO
im getting 100-110 fps with the lowest possible setting on gods green earth EVERYthing OFF . 1280 reso.

Well basically AMD chips use straight 'cores', so there is (imagine) 2, 4, 6 or 8 'workers' standing there and you 'toss in the middle' work (data code) for them to do. The problem for AMD is the lack of a threading engine (like Intel Hyper Threading) to organize the workers (the CPU Cores) to allocate the work efficiently, organize it in a way that is optimally using each core, then also how to take the 'chunks' and put them back together to 'pass on' to the GPU, Printer, Sound, etc. To execute in an organized efficient manner. Instead you have the 2, 4, 6 or 8 workers just grabbing at the work, doing it individually how ever they want then arguing over whom was first to get that code done and which code chunk should be handled first (could be out of order).

Intel does it the opposite way, they minimize the amount of cores (1, 2, 3, 4) and use Hyper Threading to maximize and streamline the efficiency, order, processing and organizing of the data that the less cores perform TWICE the work of a system with TWICE the cores (aka they do 400% better work for less cores). But Intel cores are on steps, so you have i3 for low level work (most AMD CPUs are compared to i3s), i5s for medium level and gaming (AMD highest end CPUs only can compete at this level, like the 8350) then finally i7s for maximum performance and heavy gaming (like the 'expected to work example I gave).

Now the new Haswell iCores are dramatically making this different that the i3 Haswell is performing at AMD 8350 and ABOVE level (running BF4 in Ultra mode and getting 60 or so FPS), while the i5 steps it up even higher. But still when paired to High end cards (i.e. take a PC with R9, insert the i3, play it, take out the i3 and put in the i5 and play it) each level is again showing it 'bottlenecks' as compared to the next level up. So you get 40ish 50s with a R9 and a i3, but with a i5 your 50s and 60s and if you went i7 .. well you get the idea.

The solution today is to pair the right video card to the right processor. Data does not read direct from the HDD to the GPU, it has to pass through RAM (to be reach in chunks) to the CPU (process what to 'do' with it and what component will 'do' that), so they are still in the equation. Many previous games were coded that the CPU was just passing it along with out much processing, but now games (like BF4 for example) NEED the CPU to perform processes FOR the game itself, outside of the GPU rendering graphics on the screen. So there is more dependency on the CPU to do 'more'.
