yes, you can choose whatever you want for the parameter. I suspect the book or teacher or whatever has some principle about "choose the parameter that gives no fractions, and has the X coefficient as a positive number".

Yes, I assumed that I would be sacrificing zoom. I know 35x is impossible on a larger sensor. I will look into those cameras xQubeZx, thanks!

I'm looking to improve my camera for $500 CAD I've attached a few photos that I've taken with my current: Canon SX30is (1/2.3" (6.17 x 4.55 mm) sensor, 35x optical zoom 24mm-840mm) it's from 2010. I take photos while hiking, with family and at the zoo. I've tried to attach a representative sample of the types of photos I take: Closeups in good light family candids in low light zoomed in at the zoo wider shots outside I want to improve: -general image resolution -Low light performance -camera settings control I want to keep (as much as possible) -no noise on shutter release -zoom -Macro I want to do this all with a budget of about $500 CAD. I've been looking at DSLR (noisy shutter, bad for candids) mirrorless (probably best bet, with the bigger sensor) or advanced point and shoot. I suspect I will go with a used camera from a shop where I can test them out. What should camera would be a good bet? What should I be looking for?

BIOS update fixed it!

no, I can't, there is no other PC I can play with. I was thinking of bringing it all to a local PC shop to see what they find.

The old card works fine, still. The old card uses two 6 pin connectors. RX480 uses 1x8 pin My PSU has a single cable with two 6+2 pin connectors, so I used that cable for the both 6 pin in old, and a 6+2 pin for the new (tried using both connectors, neither work).

I just received a new GPU: rx 480 https://ca.msi.com/Graphics-card/Radeon-RX-480-GAMING-X-8G.html#hero-overview Put it in my computer, and it does not boot at all (no beeps even) black screen, then no signal after a bit. The card has lights and fans that do light and spin. With the old GPU it still works fine (using it now). When it boots normally there are beeps before I get the BIOS screen. Current parts: mobo: P67a G43 (original BIOS) CPU: i5 2500k PSU: xfx 550w details: http://ca.pcpartpicker.com/list/KqgMwV Causes I've thought of: 1. BIOS needs an update (thought I saw this for some other people with similar parts) 2. GPU is DOA

I was concerned about compatibility I'm sure the speed, whatever it is, will be an upgrade from my current GPU

I have a P67 motherboard with i5 2500k CPU I want to upgrade my GPU from the current amd hd 6870 to rx480. will it work? do I need to update the BIOS? (currently running v1.10 "wmic bios get smbiosbiosversion SMBIOSBIOSVersion V1.10") This is my Motherboard: https://ca.msi.com/Motherboard/support/P67AG43_B3.html#down-bios Does anyone have experience running an RX480 on a motherboard of that vintage? Other specs: http://ca.pcpartpicker.com/list/KqgMwV The PSU and SSD were new last year, the rest were bought about 5 years ago.

I've been using a G602 since Christmas. It feels solid in the hand, I don't know what it would need to be "premium". I'm no pro-gamer, mostly I play Diablo, and strategy games. I've had it set to endurance mode the whole time and haven't noticed any issues with accuracy and such. Also the battery level still indicates 5/5 full. I haven't yet tried FPS, but given that other mouse driven (but not reaction time) games seem fine, I don't expect I will have issues. However I am definitely no pro-gamer: I'm quite certain my personal reaction time and hand-mouse accuracy is weak compared to other people. The two AA batteries are located towards the rear of the mouse, so the balance is at the rear, which is noticeable if you pick it up.

Excellent I really don't want to add that expense if it's not needed. as for form factor: lots of space under the desk and it currently has a mid tower anyway. I think he has an SD card reader right now, that would be easy to put in the new system. Thanks for all the responses!

My parents have told me they want a new PC. I built my own gaming PC a few years back. They use their computer mostly for Facebook, web browsing and photo editing. My dad is an amateur photographer and takes lots of photos and likes to edit them in photoshop, nothing too crazy though. Budget: $700 ish. I've put together some ideas on pcpartpicker ( example: http://ca.pcpartpicker.com/p/RpLDP6 ), but I don't really know where I should be spending the money. What would be a good CPU? Do I need a GPU? What should I spend on RAM? I think they already have a good sized hard drive, so I would think a single SSD for the OS would be enough. We are in Canada, and I live a day's drive away, so this part list will probably be given to a PC store that can build it for them and give them a warranty.

Thanks! so Windows 10 thinks device=motherboard, I will upgrade to 10 then.

I can't find a clear answer to this. I have a 4 year old PC I built with Windows 7. I want to upgrade to Windows 10 and get an SSD. If I do the Win10 upgrade first will it complain about being moved over to an SSD later? I know windows 10 can be reinstalled on the same device, but it seems MS is unclear about what a new device means in terms of hardware components. Does anyone have experience in putting a brand new drive in a PC with a Windows 10 upgrade and moving the OS over to the new drive?

okay, I'll look into those, thanks!
